How to: Jailbreak/Unlock iPhone 3.0 - Windows PC redsn0w Edition


Disclaimer - Neither TiPb nor I take any responsibility for any problems/issues/bricking/etc. that may occur while using this software to modify your iPhone. Please be aware of what you are doing. This will NOT work with iPhone 3GS.

There has been a lot of buzz going on in the forums regarding jailbreaking the iPhone 3.0 software lately, and a lot of questions to go along with it!. Today we’re going to take a deeper look at the exact steps you have to take to get your iPhone 3G with the 3.0 software, jailbroken on your Windows PC machine. We used Windows XP in this example, but Windows Vista shoul

Let’s get started, after the jump!

Get the tools

First and foremost make sure your iPhone is updated to the 3.0 firmware. If you’re not yet running 3.0, update via iTunes.

All good? Okay, next make sure your iPhone is not connected to your PC. Next you will need to download the following files:

Jailbreak Process

Now double click on the redsn0w file you just download to open the redsn0w application. You will then be prompted to select the 3.0 IPSW file you downloaded. Do as instructed now. Once it is successfully identified press next to continue.


Now you will have to select whether you'd like Cydia, Icy, or both installed on your phone. You must install at least one of them. Make sure your choices are checked and press next.


Next you will be connecting your iPhone 3G to your PC. Once your device is connected, hold the power button until the "Slide to Power Off" appears - then slide to power it off. Press next.


Redsn0w will not put your iPhone 3G into DFU mode. Be sure to follow the onscreen instructions exactly. Start by holding down the power button for 3 seconds.


Hold down both both the power button as well as the home button for 10 seconds.


Finally release the power button while continuing to hold the home button down until redsn0w detects your iPhone 3G.


The device will now reboot once it is detected by redsn0w.


Redsn0w will now begin the process of uploading the new ramdisk. Once this is complete you will be notified that the jailbreak process is complete. Click the Finish button.

Even though redsn0w completed it's process your iPhone will still be finishing up. This can take up to 5 minutes. Be patient, when it's done you will have a jailbroken iPhone 3G with Cydia/Icy on the SpringBoard.

Unlocking Process

Now if you are looking to unlock your iPhone follow these steps below.

  • If you are unlocking for T-Mobile USA be sure to disable 3G.

  • Run Cydia or Icy

  • Add the repo to Cydia or Icy. That last “o” is actually the number zero “0”.

  • Search for ‘ultrasn0w’ in cydia or icy and install ultrasn0w.

  • Reboot your iPhone 3G.

Enjoy your freshly unlocked iPhone 3G running the 3.0 software!

How to: Jailbreak/Unlock iPhone 3.0 - Windows PC redsn0w Edition



I am having an issue:
1) Run Cydia or Icy
2) Add the repo to Cydia or Icy. That last “o” is actually the number zero “0”.
3) Search for ‘ultrasn0w’ in cydia or icy and install ultrasn0w.

I did a jailbreak on my iPhone 3.0 on Tuesday as a first timer using Redsnow 0.7.2. It only took about 15 minutes total and most of that was just sitting there watching my phone and PC do it's thing.
Jailbreaking was the smartest thing I've ever done with my iPhone. Even if you only install SBSettings, it makes your iPhone so much easier to use. Everything is completely stable and working great.

@mike add the .com link to the sources section in cydia. You will then be able to search for and install ultrasn0w.

Mike, for step 2 you need to "add" the source to Cydia before you can search for ultrasn0w. To add the source: open Cydia, wait for it to stop loading, tap Manage (on the bottom bar), tap Sources, tap Edit (in the top bar), then tap Add on the top left. Enter "" without the quotes, then tap "Add Source". Once it's added successfully, go to the Search tab on the bottom and search for ultrasn0w. After finding it, tap Install, then Confirm.

jailbroke my iphone exectly. used it for half hour, sudnley all icons from menu vanished, not even sms,contacts,camera.... completly empty.
i still can recive calls and sms but cant do eny thing else.
i will try to do this proces again!

@Daniel, same process but you will need to download a different IPSW file. The file I attached to this guide is for iPhone 3G only.

@ Ben
I have Vista.
redsn0w stopped responding the first time I ran it. Started over and it ran just fine.

when i go into cydia, it asks to update essentials. i clicked "update essentials" and it says "error. Sub-process /usr/bin/dpkg returned an error code (2)." please help

@Steve #23:
Don't count on it. That mode is buggy as hell, and every virtualization platform I've tried has problems when installing new software releases. Most virt machines work well enough for Itunes syncing, but usually when the phone starts disconnecting and re-connecting it crashes either the virtual machine or the host machine.

Sorry i meant can i use the latest version of itunes after im done jailbreaking the 3g? Is it safe to sync or what? I dont see anyone askung this question.

I was looking forward for jailbreaking iphone 3g 3.0. Thanks guys you did the awesome job by finding way to jailbreak 3.0 again Now my phone is free again.

iTunes 8.2 works fine after the jailbreak. This is the latest version.
Also, install and use Cydia but not Icy. Icy doesn't work well on 3.0 yet.

I got redsn0w to open but I can't find the ipsw file anywhere. There is no .IPSW file in .zip file from the link for the OS provided. I also searched my computer for "*.ipsw" and get nothing. Has anyone else seen this happen? Is it different in Windows?

the Ipsw file is the same file you would download from apple to install the iPhone OS. It is also the file you downloaded when you updated to 3.0. Search on Youtube for iPhone 3.0 jailbreak. There is a video which lists a link to all the different iPhone Ipsw versions depending on what version you have (2g or 3g).

took me a while at first but was able to get it up and is running so glad my iphone is jailbroken again great job guys keep up the good work

I did this exactly as it said and my iPhone 2G says "No Service" I believe I did something wrong and have been searching all over the sprawling wasteland they dare to call the internet and am unable to find a definite answer of how to correct this. Any help is deeply appreciated. Thank you!

I still dont understand the ispw situation. I downloaded the file and what i download is a zip file. From there once you have downloaded the zip file what do you do?

can anyone help help me fix the error i get when trying to install ultrasn0w from cydia...on the last step and keep getting an error..

Yeah Redsn0w crashes often on Windows Vista but it will work if you do not install Icy.
I get a lot of crashes from Cydia with this 3.0 upgrade.
I cannot get OpenSSL/SSH to install due to folder missing(Same with ICY)
Cydia will only work if you don't restore your info from a backup.
If you sync with your older iTunes info, your existing icons will go away. you'll have to restore 3.0 to get them back.
There is no way to go back to 2.2.1 either. You're stuck with 3.0 until a more stable version comes out... i'd just wait for that! :(

i download red snow...and i downloaded the IPSW file ..but i still cant see it on when i hit browse :S... somebody help ..i got iphone 3g 16 gig and i got the latest 3.0

hey i need help... redsn0w has stopped working on me several times mid-jailbreak.. forcing me to restore my phone..... HELP?!?!?!

yo, man! awesome... it works. so, if you by any chance get an error regarding the DFU Mode not recognized (as i did) it's probably because you don't have iTunes installed. hope this helps.

This worked great on a RC of Win7, on my 2nd gen iPhone (the 3G, right before the 3GS). Thanks a bundle.

I have done all the jailbreaking steps but when I try to unlock it so I can use it on T-Mobile, Cydia will not load up because it says I have no internet connection.
I am using my grandma'a at&t sim card to try and unlock it but she doesnt have internet on her plan..but I am connected to Wi-Fi but it wont help in loading any web pages..what am I supposed to do in order to unlock the phone?? PLEASE HELP ASAP!!

I tried several time to unzip the zip file linked to iPhone OS 3.0 for iPhone 3G(IPSW) provided above but in the zip file is a whole bunch of different files. Not the tradition .ipsw file I'm used to. What's wrong with my approach?

Hey guys, trying to jailbreak my iphone for the first time in ages. It's a 3g 8gb running 3.0.
When it gets to the "waiting for reboot" it just stays there ... I left it for about an hour and still no change.
Is there something I should be doing ... like pressing any of the buttons or could there be something else I have missed.
I am running Vista x86 and have changed the compatibility options to xp of redsn0w and am running it as administrator.

To people who have problems figuring out how to continue installing redsn0w because it asks for you to locate your IPSW firmware, (i wasn’t able to find mine, in winXP) I went here and downloaded this file: I had the same problem. Worked like a charm.

i got a huge problem... i had a jailbroken Iphone, and i Loocked it. Now i got to fix it on itunes, but the screen on the iphone is not working... but when i connected it to my computer, i can hear that sound from the computer but no responding from my iphone:s

Can somebody answer the question everybody is asking?!?
Does this work for the 1st gen iPhones running 3.0.

if I do the jailbreak process, and after weeks wanna go back to original OS, what I need to do?
Just restore backup with itunes?

YES! BUT you need a different IPSW file. The iPhone 3G has a different IPSW file than the iPhone first gen.

@Carlos E.:
Just go to itunes and restore you iPhone from there. It shouldnt take more than an hour to restore. Also, once you jailbreak you won't want to go back...

waited a while to jbreak 3G 3.0. Finally, this is great. wondering when will i get to jbreak 3GS.
thanks a load guys.

hi, i have tried this over 20 times and it has not worked the phone follows instructions but it does not reboot itself. can you help me? what shall i do?

this is fantastic - what you guys have done is tremendous. It took a little while to do - but it seems to be working now. Many Thanks from a global traveler with 10 sim cards to use!!

I just upgraded my 1st Gen 8GB Iphone to 3.0 firmware and download the ISPW. Using RedSnow to jailbreak and Ultrasn0w to unlock. I am using it right now and notice some delay when open apps...

hey guys.....i have downloaded both
iphone 1,13.07A341custom_restore.ipsw and also
redsnow 7.2..............i also have updated my phone to the new OS 3.0.....however when i open redsnow and browse the ipsw and selected it, redsnow came with an error that its unable to process the firmware.......can anyone help?

had 2.2.1 jailbreak, several apps in "Categories" did the 3.0 update and successfully jailbroke w/ redsn0w, but the apps i had in "Categories" folders are now invisible. Also i am unable to do anything in Cydia...keep getting errors...any ideas anyone?

Update to post 68 regarding Cydia errors: this relates to a required "Essential Upgrade" with three options: "Upgrade Essential", "Complete Upgrade", and "Ignore (Temporary)", with both upgrade options ending in errors, and ignore doesn't do anything, but trying to install any package ends in error. Please help? I've got many apps "locked in 'jail'" since the 3.0 update.

outpour I get the same error message... I cant update any packages or install any either. I dunno what to do...

just jailbroke my 3g with 3.0 firmware as well as my 1st gen iphone with 3.0 firmware and now the wi-fi connection isn't working with either of them on a connection that had worked previously. any help?

helpp once i try to unlock my iphone 3g nothing happens I wad able to download ultrasn0w bit when I rin the application even though ir saysss complete and I turn off and on my phone nothing happens itt just sayss searching or no sim card...what should I do

There is no ipsw file in the zip file that downloads from the link above. Where do you get this file?

thanks. i couldn't get it to work with the etc. it worked great when i installed but left off icy. thanks

For those having difficulty locating the IPSW file after downloading it, do not bother to look for it, you probably wouldn't find it. Use Firefox to download it instead, only then you can locate it. Hope this helps.

If you have downloaded the file "iPhone1,23.07A341Restore.ZIP just rename it to iPhone1,23.07A341Restore.ipsw then it works fine.

should i take out icy? but it seems like everytime i reboot it wouldn't let me take it out...weird? what u think i should do? restored everything? will i lose my contacts then?

Hey Everyone.
My was jailbroken by the guy I bought it from, he installed icy. I need to unlock the phone though I am unsure what I am supposed to do on the step that tells me to reboot.
Should iTunes be open when I do it.Should my sim card be in the phone or out.

And should I make an attempt to open up redsn0w or will it happen if I wait with the phone off and plugged in.

Can someone please advise me to find the ISPW file for the first generation so i can unlock my phone as well?

After you unlock the iphone for tmobile .. is it possible to get it back to normal .. if so, how?

i cant get find the frmwire even after i download it i cant see were it is??? is it only possible to do this on mac??? :s

anyone can help me, after jailbreak and unlock by adding ultrasn0w my iPhone keep says 'No SIM installed' eventhough i've inserted the SIM card...

I've solved my problem with the following steps:

  • restore the iPhone using iTunes to factory.
  • followed the normal step to jailbreak selecting Cydia.
  • Now I can see the cydia icon =)
  • add the repository
  • Now I can search for the ultrasn0w =)
  • Now I'm happy =) hahaha


i recenlty added winterboard and had set the dock to transparent then downloaded a few other themes from cydia. few days ago my dock was no longer able to become transparent. I don't know if it was a problem with wb or what but i reinstalled everything then removed everything else i dl from cydia and still wasn't able to have a transparent dock any ideas? i'm having to restore my phone then re jailbreak it not a very fun experience putting all the music back on.

well now that i restored my phone to factory settings then re-jailbroke it the essential upgrades that i need to run cydia are not working. disk-dev is where i'm getting an "internal error, says could not perform immediate configuration (2) on essential" wtf? any help?

do I need to have an internet connection or a wi-fi connection to add ultrasn0w?!
Cause in every iPhone I see has there wi-fi on while doing it...

Anyone having problems with the software crashing during the "ramdisk" part, believe it or not if you grab the window and continuously shake it (typical windows), it actually doesn't crash. i couldn't believe this so i tried it myself and it worked. RESULT!!

in order to use the applications from cydia do i have to download winterboard or anything else. if so, when can i get that from or how do i install it?

I've tried twice to do this and everytime it stops working, and a "redsnow has stopped working" icon appears giving me the choice of shutting down or finding a solution online.
Any advice would be great!

Every time I go to download the 3.0 firmware for the iPhone 3G I get some zip file, which when opened contains a bunch of .dmg files and an assortment of other random files...none of which are the ipsw. I've downloaded/saved the files from numerous sources so I have no idea what the problem is. If it helps, I'm on a PC running Windows XP. Please help!

PLease someone answer me this questions:
If I jailbreak my iPhone, will my contacts, sms messages, bookmarks, etc will be saved?
Will cydia still have the same apps, like Winterboard, Categories, iTv, imobilecinema, mobile theater, i file, five column springboard.

I unlocked my my iPhone with Cydia and ultrasn0w.
I am able to use my phone in India, but I am not able to send SMS, can some one please help.

I'm on Windows XP pro SP3, iPod Touch 2G with OS 3.0, Redsn0w 0.7.2. During the jailbreak operation, redsn0w successfully identify the 3.0 firmware, then I click next, Dialogue box appear: "Preparing Jailbreak data, connecting to sever" Then redsn0w gone (Disappear!).
I repeat around 100 times, it still the same. I try with another PC it still the same. Before I'm successfully jailbreak iPod Touch 2G and iPhone 3G. but now fail to do so..! Please help!

Can I update using itunes to OS 3.0 ? However, then how do I make an ipsw file ? Is this ipsw files the same for everyone on this planet ?

Everyone having trouble finding ULTRASNOW..
Spell it correctly
u l t r a s n 0(this is a Zero)w.
Everyone having issues with “error. Sub-process /usr/bin/dpkg returned an error code (2).”
Rejailbreak and only install cydia. if you install both icy and cydia their is a file that gets bashed and causes both to fail. I fixed my iphone by rejailbreaking and only loading cydia, after i updated all of cydia, i loaded ICY from cydia

Hey I recently jailbroke my 3G 3.0 iphone and i have the cydia icon and was able to use the ultra snow. the problem im having is the fact that i am unable to connect to the internet via 3G/E ..keeps giving me a error message saying..

hey guys...Im trying to jailbreak and unlock my iphone 3g on 3.0 OS. I would like to know whether my contact info in my iphone would be deleted in this processes. if yes, how to have a back up?

Hi everyone,i appreciate the guide and information present here although im having difficulties locating the .ipsw file despite downloading several versions of the file listed on this page. Id appreciate any help as i cant go any further and it s worrying me. Thanks :)

I jailbroke my iPhone 3G but when I ran Cydia for the 1st time. I did the complete upgrade, but it failed and I cannot install anything.
Did that happen to any if you??

Hi I have a doubt what happen if I unlock & jailbreak my iphone in a pc can I use it in my mac or what? I now that there's different firwares for mac and pc but can I unlock & jailbreak an iphone in a pc to be use in a MAC?

When I jailbroke my iPhone I chose Icy instead of Cydia, wrong choice I couldn't get anything to work right. I'm going to try an jailbreak it again but this time I'm only going to install only Cydia see if that works.

Thank you sooooooooooooooooo very muchhhhhhhhhhhhhhhhhh
Its Done in first attempt
You are awesome !!!!!!!11
Thanks a ton once again

1ST QUESTION: If I unlock my iphone 3g with tmobile, what kinda data plan would i need ??
2ND QUESTION: After unlocking would i be able to go back to normal like using att again??

As a couple of people have reported, redsn0w crashes in Windows 7 RC1 if you try to install Icy. Leave that box unchecked (you may install Cydia) and all is well.

Hey guys.. You mentioned before that for the Iphone 2G it is the same process for jailbreaking it but with a different IPSW.. Which IPSW should I use after I have already update the Iphone 2G to 3.0..
Any help would be really appreciated..

HUGE problems.. Whenever i get to the downloading jailbreak data (the last step with the picture of the green arrow and hard drive) it just has that screen and the loading icon and it doesnt do anything.. I've tried it 5 times and had to restore it every time! Pleas help!

I have jail broken my iPhone 3G and also followed the steps to unlock using ultrasn0w. Everything went successful but still my iPhone does not recognise the new SIM. Is there anything else that can be done?

WOW... i was a skeptick and Did not want to jepordiz my Iphone. but I gave it a shot... it works... Its awesome.. REMEMBER when you are in the steps abouve Hold the the Home botton as long as the Jailbreaking sofware is running it could take longer then 25 sec. so hold the dame button other wise u will get an Windows ERROR message.

Salma what is your question? no internet is required to jailbreak if you have
1. iphone 3.0.ipsw (make sure u download right version for eg 2g version or 3g version)
2. redsn0w0.72
3. itunes V 8.2

i just jailbroke and no internet… anybody can help?pleaseei am desperate
please people i am here since long time reading eveything
but no one answer my question

hi francis
i have 8G iphone and have latest itunes idid jail break all looks fine i think..but i see internet wireless but doesnt conneect
i want to use my other sim says no service
i disabled 3G on the phone what should i do now?
i have got the cydia icon also.

I have few questions for you

  1. How do u say that ur phone is jailbroken?
  2. Does ur current sim card work?
  3. Does ur other sim card work on another phone?
  4. When u connect to ur wireless what is the error message do u receive?

By the way ICY is more stable and easy to use app than Cydia. People who have used ICY will notice that difference

thanks alot for your pateint
I did buy from the internet software
and i wish i didnt..because i dont get any helpthey dont answer any questions they are very good in recveing credit cards.any way..before when i inserted the sim card it was compaling that the sim card is not after i did restore and used redsnow i dot get complaine about the sim but i get no service.
internet i can see my wireless routers but i dont get IP.and if i put manuel IP still same problem when i try to browse it says device not connected to internet.

For those who have problem connecting to internet please tell me do you see the below option in the following location
General->settings->network->1. "Cellular Data Network" 2. Data Roaming 3. VPN 4. Wi-Fi
Most of you who do not have "Cellular Data Network" will have this problem. we need to add an entry in carrier.plst to enable it.

General->settings->network->1. “Enable 3G” 2. Data Roaming 3. VPN 4. Wi-Fi
this is what i have

Even after inserting the SIM Card if you are still getting "NO SERVICE" then pls check if u have the same problem in a different phone. Sometimes even if the signal is not detected due to signal coverage reception problem u would get "NO SERVICE".

I have very good signal and i changed the simto other pgones work normaly..but only in my iphone no service :-(

If 3G or Edge still aren’t working, then you probably might not have officially activated them through carrier, so instead of needing to do that, try setting your Data Roaming Options to On, which helps bypass this problem, since it forces the phone to connect to “roaming” facilities such as 3G.

To do that go to your Settings>General>Network and make sure you have both 3G Enabled and Data Roaming set to On.

Looks like U have JAILBROKEN the iphone but have UNLOCKED the iphone.
Remember JAILBREAKING is differnt and UNLOCKING is different.

In this WebSIte i see that in the SECOND Screen shot of the JAILBREAKING Process there is no "unlock" option under install Cydia and Install ICY. the options should be as below
install Cydia
Install Icy

You should only use "iPhone1,13.07A341_Restore.ipsw" (iPhone OS 3.0) to Jialbreak

@Max Says:
June 30th, 2009 at 11:02 pm
Did u make sure you were using the correct .ipsw (if ur iphone is 2G then use 2G version
and if ur Iphone is 3G download 3G version)
Try restoring the phone to 2.2.1 and then update to OS 3.0 using iTunes V 8.2 and then jailbreak OS 3.0 with redsn0w 0.72

@ Raj Says:
July 1st, 2009 at 12:40 am
Looks like u have Jialbroken the iphone successfully but u have NOT UNLOCKED it.
U will get an option to "Unlock" in redsn0w while choosing to install cydia or icy and UNLOCK

has anyone has a problem where after they jailbroke their screen would start flashing rapidly aftering trying to launch cydia?

I've never jailbroken my phone; kinda scared. Will I lose any contacts, apps, songs, pics? Can I go back to the un-jailbroken version easily? Can I still buy regular apps from app store add new music? What will happen if I try to update to the 3.1 software with a jailbroken phone? Will it get bricked?

@ Francis
Can you post or link instructions on how to edit the plist to get the settings "Cellular Data Network" to show up? I gave my girlfriend my old iphone and she is saying the internet isn't working. I haven't had a chance to look at it myself but am assuming this is the problem.

I jailbroke my phone but after I do and after a few hours of use, it freezes up and I can't use it until I restore it, it seems like the jailbreak is unstable, can anyone help me????

Do i need to upgrade it to 3.0 OS using APPLE'S OFFICIAL 3.0 FIRMWARE (using update optin in itune)before jailbraking? or, can i use iPhone OS 3.0 for iPhone 3G (IPSW) given in this tutorial to upgrade my phone to 3.0 OS?

@ Nick Says:
July 1st, 2009 at 6:25 pm
That is not so easy and again not so difficult.
First of all you need an Iphone PC Suite. so that we can navigate into the files of iphone.
By the way what carrier are u using?

@ lee Says:
July 1st, 2009 at 11:28 am
Usually Redsn0w 0.72 is a .rar file. SO you will need "winrar" application to unrar the file
to use the redsn0w.exe

@ Carlos V. Says:
July 1st, 2009 at 12:41 pm
I can only think of the following

  1. Are u using the correct .ipsw for ur 3G version?
    2 Did u follow the correct method of seeting the phone into DFU Mode?
  2. Did u first of all install OS 3.0 Update through Itunes V 8.2 and then did redSn0w ?

@ G Bananas Says:
July 1st, 2009 at 3:08 pm
You will not lose your contacts songs or pics if you have them in itunes.
To be on the safer side make sure you manually backup your photos rest you can always get it
Once your phone is jailbroken you cannot go back to "un-jailbroken" (if you meant original version)
Its a tedious process to do that.
If you update to 3.1 with a jailbroken phone you will not be able to use your SIM CARD.
Wait for the update until 3.1 jailbreaking tool is released (which will not be any sooner)
coz the 3.1 beta is only released now.

@ Roshan Says:
July 2nd, 2009 at 1:09 am
You NEED TO FIRST UPDATE USING iTUNES with OS 3.0 and then jailbreak
using the .ipsw and the redsnow downloading in this website

IS it 1G "IPOD" or "iPHONE"?
There is a seperate version of ipsw available for 1g/2g version iphone (google it and find as there are lots of sites available
try "" and download the version for 2G (if it is an iphone)
there is a seperate version for "iPOD"

@ tan Says:

Difference Iphone 1G vs iphone 2G
The biggest difference is that the 2nd generation iPhone has 3G internet connectivity
which the first generation lacks. Take a look at the link below for a side-by-side spec comparison. The 2G model refers to the 1st generation
and the 3G model is the 2nd generation iPhone.

  1. Did u jailbreak using the correct version of .ipsw (2g for 2G and 3G ipsw for 3G phones)
  2. Before Jailbreaking did u first update ur iphone using iTunes v 8.2 to OS 3.0?

First u need to update to OS 3.0 and then Jailbreak using the correct version of ipsw (by downloading it )
I have posted the link for "tan" in this forum from where you can download the correct .ipsw

Cydia is very unstable after Jailbreaking OS 3.0. Use "Icy" its far more stable and better in most of the ways. People who have used it will agree with me.

Those who have problem connecting to internet please tell me do you see the below option in the following location
General->settings->network->1. “Cellular Data Network” 2. Data Roaming 3. VPN 4. Wi-Fi
Most of you who do not have “Cellular Data Network” will have this problem. we need to add an entry in carrier.plst to enable it.
But if you do have then go to “Cellular Data Network” and then to "APN" and enter your data plan details.
This will solve your "you must have a cellular data plan to use this service"

Well...jailbroke my phone for the first time. It went way smoother than I thought; did it on Vista without a single problem. But Cydia sometimes crashes when i download a theme. Haven't really messed with it all that much; what are some apps I should download first?

I am using T-Mobile on a 3G iphone. Everything else works great, wifi, sms, phone, just no edge. If you could post a good walk through on how to edit the plist that would be great. Difficulty isn't a problem as long as the instructions are written for someone who's never done it.
BTW, You are awesome for helping all these people get their phones working.

Jailbroke on windows 7 beta with 3.0 worked on my pc but do NOT install icy. I did the first time and cydia would not load.

Need Help!! When i donwload "iPhone 3.0 firmware" for windows, WinRAR extracts it but there are mutiple files and none of them are .ispw formate. How do I get this extension. I did this for my iPod Touch and the file that was downloaded was a iTunes cube with the .ispw extension. What am I doing wrong???

I have a 3g with updated 3.0 software i did all the steps everything went smooth phone is running great, i only downloaded Icy and when i try to go download something, all it says is "Couldn't Resolve Host name" then gives me the source website no matter which source. any ideas?

does it take long waiting for the reboot cuase i fallowed everything and is not showing thats is loading in the bar ughhhh i done it twice already because is taking long to upload please help

I have the same problem with my phone being blank now for the last 5-10 mins now......what are my options?

ok so i was able to cancel the install and try the process over again.....and each time it looks to me like its trying to reboot and install the jail break software, but then the phone just sits there and doesnt do anything for as long as I let it sit there. not too sure what to do this point except not jail break my phone....oh well sucks to be me then huh. lol

I have a 3g that still has the itunes symbol at the top of the screen with the little usb cord on the bottom... Itunes saw the phone once and asked if I wanted to install 3.0 firmware via Itunes 8.2. I guess my question would be, how do I get past the Itunes USB screen so I could actually get to the application screen?

This symobilzation means that you are in "Recovery Mode" So cannot see any applications in here. You can only update the firmware by doing Shift + Restore on Itunes and that will give you the browse option to select the downloaded ipsw file to update. So i am not sure which step you have completed.

It means that your iPhone is not "UNLOCKED". Remember that Jailbreaking is different and Unlocking is different.
If you Jailbreak your phone it will give you the icons otherwise it lock on a emergency call only screen
If you need to unlock then you should have checked "unlock" which will be in the screen on redsn0w 0.72 where you check "install Cydia" or "install Icy"

Try updating your phone using itunes v 8.2 to OS 3.0 and then jailbreak it once again using Redsn0w 0372.

  1. Did u first update using itunes v8.2 to OS 3.0 and then Jailbreak it with redsnow ?
  2. Are u using the correct version of ipsw? (unless you are not using a 3G phone)

@ Ryan Says:

If you get that msg, try to refresh the sources. You just need to refresh the source by clicking the refresh button that you will find on the top left corner when u go to "sources" tab at the bottom.
Unlike Cydia , ICY already has all the mail sources added however when u hit on edit and then add or the "+" sign and select "add all " and then select done and try refreshing again for two or four times.
This way it worked for me

  1. You should not the .ipsw file using Winrar
  2. There is no iphone 3.0 firmware specifically for "Windows" or "Mac" except for " Redsn0w for Windows" and "ultrasn0w for mac"
  3. You first connect ur iphone to your itunes and then click on update which will update to OS 3.0

NOTE: If your phone is not a 3G iphone then dont use the .ipsw downloaded from this site. I have already posted the link for downloading .ipsw for iphone 2G in one of the posts for "tan" which is ""
4.Download RedSn0w and unrar is package using winrar and follow the instructions as given in this site
Rest is almost self-explanatory

I will try to make it as simple as possible however i am not good at explaining and forgive me for that.

  1. There is a carrier .plst file which will be under system ->library-carrier bundle->here you will find a list of carriers like vodafone , at&t , orange and many more.
  2. here you need to choose the correct carrier folder which contains "TMobile_bg.bundle" in which i presume "bg" represents the country (bulgaria may be)
  3. So there are about 12 "TMobile_(country name).bundle " SO you need to select your country folder in which u will find 4 files and one of which is "carrier.plist "
  4. If you open that file with an editor you will see an entry as below


  2. A normal carrier.plst which does not have EDGE option will look like below


  1. So once u add the entry and save it then restart your iphone and voilaa!! you should have "cellular data network" in which you can enter the "apn" settings
  2. NOW THE PROBLEM IS YOU NEED A "IPHONE FILE MANAGER" OR "IPHONE PC SUITE" to get to navigate through to reach the carrier.plst
  3. This is the hard part as you need to download the iphone pc suite . I downloaded a Korean pcsuite and installed it . I am not a Korean to understand the language but i just logically clicked on buttons and had it installed and then there was option to change the language to English(which was not easy was going through every menu) and this is done a WINDOWS machine

Hope this helps you buddy.

I will not be online for the next two days so if you have any other queries pls post it and i will answer it on monday!

hello guys i need help i got my iphone 3g jailbroken and unlocked so i was running 3.0 firmware then i downloaded an mms application and then my phone wouldnt boot up. it just got stuck at the apple sign. i tried jailbreaking it again but im getting no service now. please help..

I am running firmware 3.0 (7a431) on my iPhone - i have tried quickpwn and redsn0w with no success it appears that my iPhone wont go into DFU mode, i have tried reverting back to 2.2.1 and many times trying different ways of getting it into DFU mode with no success anyone else experienced this or no of the answer?

Thank you guys for your job, as step by step i follow you & finally " voila " it's 100% working (jailbreak & unlock) in Canada it's working on both Rogers & Fido, my Iphone is 3g - 3.0.
Thanks again for the way you explaine it... Good job from you.

I am having the same problem apparently lots of people are having; All steps go smooth until the reboot and the install stops at "WAITING FOR REBOOT" How do I ensure that I get past this and successfully jailbreak my phone?

I bought a 16g 3G with 2.2.1 hadn't jailbroken it, i'd upgraded to 3.0 about 2 weeks ago, just jailbroke it, installed Cydia only, took 5 minutes, no issues so far.

Since I jailbroke my iphone 3G it works perfectly, but the battery life runs out rapidly. this problem improve a little with the recommendations posted for apple. Please any suggestions it makes me crazy to charge the iphone at every moment.

Hey Guys, I just got a 2nd gen iphone with 3.0 update on it,what do i need to do to get this thing jailbroke?Be gentle this is my first time...Thanks

Thanks for everyones responses. I ended up figuring out why I was doing wrong however when I try downloading the rep0666 I get this message saying Did not Find Repository. It says it's a Legacy Installer and it's not supported and I need the exact repository URL. Does anyone know of an alternate URL that will work? I think it might be because I restored an old iPhone to the phone I'm currently on. Can anyone help me on this topic?

Hey guys. I just bought an ipod touch 16 gig, updated to 3.o, jailbroke no problems. I then bought a 32 gig and tried the same exact process and when redsn0w tries to reboot it after DFU mode, the ipod, won't reboot. I end up having to restore with itunes. Let me back up though, the first time I did it, I was using a laptop with vista basic. This laptop is vista home premium. Not sure if that's what's causing the problem or not. Also I used the itunes folder where the 3.0 restore was located, instead of downloading it from this site. Doesn't seem like that part would matter considering it's not getting to the point where it uploads. Once I had it go all the way through, but the ipod wasn't powered on, so I don't know how it thought it jailbroke it. Did Apple release something in the past few days in their 3.0 upgrade that prevents redsn0w from rebooting the ipod touch during the jailbreak process? Pulling my hair out, would love some feedback. or damnedid on aol messenger.

I found the problem.... Just be sure to use the ipsw from your itunes folder on your computer. i got a little further. redsn0w is still crashing but i'm thinking i'll have that fixed in no time.

Fixed the crashing by installing ICY first, then going back through and installing CYDIA. So far so good. Good luck with those struggling. :)

ok, i did every step, when it came to choosing cydia and icy, i untick icy and only install cydia. now that my phone is unlocked using ultrasn0w (yay!) i can't upgrade cydia. when i selected complete upgrade, when it's downloading, i always get the error "POSIX Connection reset by peers" with repo above it... i just can't download anything from his repo source? any help? my wifi works fine, i redid everything three times and it still doesn't work?? is saurik's repo down or something that i can't download them? thx for ur help

i have downloaded redsnow. but when i trie to download os 3.0 and i put in a folder and then run redsnow and wan to browse to that folder where i put the os file in the folder is empty.

hey for people who are stuck at the reboot title its because u have the wrong ipsw and need to make sure its the exaclt model.
I need help unlocking my iphone 3g. i have done everything after iv jailbreakin it. i eneter thr repository but it keeps saying something about legacy installer need help

im using cydia and i put the failed attempted source and came up to a pop up claiming it could not find repository and saying only capable of exact respositories im lost ....head spining.....

also my cydia wont let me sometimes click on links. i click on them it seems to load but then just quits and goes back to the springboard. is that the phone or the cydia program. ive uninstalled it once but its doing the same thing, is this normal or did i do sumthing wrong

I'm having exactly the same problem. I tried it again, but it got stuck at reboot again.
I don't get it......?!

ur problem is the ipsw. i had the same problem but i back tracked. Make sure u have the right iphone firmware downloaded on ur desktop. i had the first gen downloaded but my iphone was a 2g iphone 3g and i was wondering why it would stay at "waiting to reboot". i hope that helps...

i am having trouble unlocking my phone. if i am trying to unlock for t-mobile do i need t-zones first in order to unlock . im am also having trouble connecting to internet... any suggestions

For people who can't upgrade essentials, just jailbrake your device again. Dont restore just use redsn0w again.

Hello I have just updated my iphone 3G to 3.0 OS when I had it jailed broken in 2.2.1 now When I click browse and I go to the folder 3.0 and then I can only proceed to look in the next folders and there is no .ispw or something like that to click open on help please thanks

Hi guys,
This is my first time jailbreaking so I need some quick clarifications. Hope someone here will help me out.
I live in India and I have a Vodafone locked iPhone 3G and all I want to do is jailbreak it,. I DO NOT want to unlock. I just want know if:
1) This is completely reversible (if I just restore in iTunes will my iPhone be back in jail like it was the day i bought it?)
2) Can I still install apps from the AppStore the normal way cuz I have loads of free apps the I would like to continue using.
3) Would adding music, vids, photos etc still be done the same way (through iTunes)?
Sorry about the n00b questions but it is my first time and im a lil apprhensive.

When the iphone reboot it give me the icon of a USB cord and the Itunes icon. Look like its telling me to run Itunes. When I run Itunes the software is telling me the phone is in dev mode and I need to restore it. What am I doing wrong?

i get an error like ( sub-process/usr/bin/dpkg returned an error code (2) when i install application can anyone have an idea thanks..

I jailbroken and unlocked my phone and everything works great, but later in the day, I am not receiving incoming calls. I can still make calls, retrieve data but do not get the calls when people called. Rather sometimes I get a missed called message or when there's a vm. Does anyone have the same problem? Pleaseeee help!!! Many thanks.

I downloaded everything fine but when I try to open redsnow it say file corrupt what should I do?

Run redsnow from the zipped folder. Just click on it and you will be asked to "extract, run, or cancel". Don't extract, just run it. Worked for me.

thanks dude itz working i can use any network i m happy thankzzzzzzzzzzzz a lot dudeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Hi All,
I went through all the Q&A on this page as well on other websites. Many have asked the question I am going to ask but no one have replied. Please Help !!!
I have all the required files downloaded in a folder did all the steps exactly (for about 30 different times). I can get to until the iphone screen goes all "White" and when it should show "Downloading Jainbraking Data" my iphone flicks once and then a black blank screen for infinite time, how ever the redsn0w software says its "Done".
Can someone help me on this please.

i unlocked my iphone with the latest redsnow and it worked. later i did a restore and tried to unlock it again but my iphone just shows the network signal, network name and slide for emergency. itried using redsnow again but it doesnt get past the waiting to reboot stage and even when it does it doesnt show the pineapple logo on the apple screen. i really need to get this done.

K everyone who is having problem in cydia with the sub-process update error (2). What you need to do is run Redsn0w again without installin icy!. Only cydia!
