Updated: iPhone 3.1.2 Now Available

iPhone 3.1.2

Head on over to iTunes and start your downloads, people, because iPhone 3.1.2 (7D11) is now available!

Weighing in at 306.2 MB, Apple says:

This update contains bug fixes and improvements including the following:

  • Resolves sporadic issues that may cause iPhone not to wake from sleep
  • Resolves intermittent issue that may interrupt cellular network services until restart
  • Fixes bug that could cause occasional crash during video streaming

Update: iPod touch 3.1.2 is also out, and US readers are telling us AT&T Carrier File Update 5.6 is popping up for them as well. If you notice any other changes, please drop us a note in the comments!

So is the infamous "coma mode" fixed? If you've been having trouble, and you do the update, let us know how it goes.

Updated: iPhone 3.1.2 Now Available


i still cant MMS, the option is there now but every picture message i have tried to send to any other phone on any other carrier always fails, any one else having this issue, I have updated to carrier file 5.5 and restarted my iphone, no go.

Thank god...my iPhone has been plagued by this ever since I updated. I will be installing as soo as I get home

nevermind as soon as the update finished i got 2 picture messages that came through successfully.

Does anyone know if this fixed the poor battery life? I haven't had any problems except for that.

@Mike: I had the same problem I went into the apple store and they ran a diagnostic and the phone was fine. ATT had to reset my messaging and data plan to get my visual voicemail and mms to work and you have to stay on them to make sure they turn your messaging back on.

It works for me. Just for grins, try hard reset.
I have heard of a one instance where one half of a couple could do MMS while the other could not. They had to call AT&T to get MMS enabled for that number. Go figure.

I'm still gonna stick with 3.0. It's been working fine for me and I'll stay on it until they force me to upgrade! ;)

@Dexter, I think 3.1.2 maybe a good option for you because I was regretting updating to 3.1, but 3.1.2 seems to have fixed any problems I was having with 3.1

If you know someone with a Mac or if you know how to use Vmware on your Windows machine, create a customized 3.1 firmware using Pwnage 3.1.3

I've been having difficulty with YouTube videos hanging halfway thru.
Another thing that's just happened today (pre update) is the non existant buttons on top and bottom of emails

I sort of did this, too. Sort of, because I installed VMWare Player as well as Leopard already installed in a VM. Pwnagetool 3.1.3 ran find in the Leopard VM. I then copied over and saved the custom firmware file, installing it from my Windows 7 iTunes install. An easier way, if you trust the source, is to find an already-generated custom firmware from someone who used Pwnagetool on a Mac and made the results available. As stated, once you have the custom firmware, you can install it from Windows.

@George how do you know it has fixed the battery issue? It hasn't been out that long

Oh Dear Gawd, if this fixes the fail Wake (Coma mode) I will be SO happy.
@George: How can you tell in the half hour its been available that it fixed your Battery issue. A simple reboot would have solved that.

Mine is still locked with 3G 3.1 05.11.07 can't unlock, can't downgrade... Cannot do anything...
Jailbreak works,if install ultrasn0w.. "Serching...." after while change to "No Service"
I hope hacker will unlock soon...

I want to upgrade but don't wanna loose the jailbreak on 3.0 3gs. Why they haven't released any official JB for 3.1 on windows! It's driving me crazy!

George is probable right, I had the same problem. My battery you could watch the percentage go down every minute (full charge used only lasted 1 hour 15. But I finally got mine fixed last week, at first I did restarts, resets, restored and used backup, still no fix but I finally did a restore and did all new setting and no backed up file used.

Usually with the big fixes, it fixes bugs I've never experienced. This time, I've had all three of those bugs! But...I'm jailbroken :(

Awesome, Will grab this in a bit. Was once jailbroken but dont really miss it and I got tired with the constant cat and mouse games with firmware updates! :D

I'll stick with 3.0.1 until it ra1ns black :-P
Looks like blackra1n jb will work with 3.1.2 -- thanks to Apple for getting this to geohot so soon haha.

I'm downloading this from iTunes but instead from a website so I can keep my tethering : ) on my iPhone that isn't jailbroken.

Very simple process. Follow the instructions for updating carrier files without updating to 3.1 and instead point it to custom firmware file. iTunes and your phone will take care of the rest.
1)Download custom firmware
2)Open iTunes, go HOLD SHIFT and click RESTORE. Point it to custom ipsw.
3)Enjoy. (Don't worry when your AT&T disappears, this is normal. There's an application you can download from Cydia that you can use to put AT&T back or whatever the heck you want.

@ Nassblu; Every post on every website indicates it will only work on 3.0 or 3.0.1 jailbroken iPhone. If u updated to 3.1 using apple official release U CANNOT JAILBREAK FOR NOW! READ BEFORE U ASK QUESTION...

For now, you're screwed. Unless you saved your EICD to Cydia. If you don't know what I'm talking about, you're screwed.
Follow geohot, iphone_dev and this website for information.
Blackra1n.com isn't a bad one to follow either.

why are ppl screwed that the dev team or jailbreakers are doing the same crap apple is. if it wasnt for i cant remember but the 3gs other jailbreak release, dev team would of waited a year.


Does anyone know what changes come with the carrier update besides the tethering data usage on the about page?

@t0m. Silly iPhone. I never made the jump from 3g to s. Why puts my update at 241mb I wonder what is the 60mb difference.

does this update fix bluetooth issues? i don't know if anyone else has this happening but ever since 3.1, my bluetooth headset is constantly disconnecting from the phone and i can't stress how annoying that is

when the 3gs first came out, dev team sat on a jailbreak, it wasn't the dev team who released a jailbreak for it, but someone else. why? they follow the same bs apple does. lets show what we can do this but no you cant have it.

Anybody notice that the little red X's that appear in the top corner when switching web pages in safari are easier to hit now? Before I would have to tap several times before the page would close.

I have the same problem with my 3gs and had it with my old 3g as well. I'll test and see if it is fixed.

@Joe McG
it still does it! Just happened after I updated. WTF?!! I never had an issue with it with my 3g or 3gs til 3.1. I use the plantronics voyager pro. Used to use the apple Bluetooth but that one sucks. Plus I'm now noticing some cracks on the bottom of my phone too...is anyone elses developing hairline cracks?

Me too. Bad, no, terrible batt life. How can my second hand 3G that's jailbroken running winterboard have better batt life than a brand spankin' new 3 GS in standby????

Just finished the update and it was quick. Or am I just use to how much time it takes. LOL I did notice that I did not have to redownload my exchange contacts, email, and calendar. Sending sms is now faster. SMS was taking for ever to send before this update.

Weird but i thought what the heck i have att ill update as soon as i did i got full service 3g when i never got it at home not even close so maybe there updating there 3g i know thats for sure for me

after having the same battery issue and speaking to Apple about it, the solution we came up with was to do a clean install and do not restore from backup...

At least this update fixed my 3G connection. 3.1 broke my wifi and this update didn't fix it. Resets and restores haven't fixed it either. Guess it's back to the apple store for me... :/

Smart Playlists & Top 25 Most Played Playlist still not syncing properly...kinda disappointed right now smh

@ Mike
I have exactly the same issue. 4 hours on the phone with AT&T, no help. 2 hours with Apple Care, they told me to restore as new phone. So I did, lost all my existing SMS info, no MMS. WTF! I'm so over this bs.

@eralwss puppy:
Already tried that. Restore and use as NEW phone. Batt life us absolutely terrible. Right. I would go to Apple, but my phone is from Australia and I'm in Cebu.

wifi doesn't seem as stable as before.
sweet! something new for me to obsess over until the next fix.


wifi doesn’t seem as stable as before.

What do you mean? What symptoms are you seeing?
WiFi seems ok for me, at least against my own router.
One issue I saw frequently with the prior release was dropping my password to my own router just because it could not connect immediately. I haven't seen this yet on this release.

Very happy with this update. Since 3.1.1, my phone has been lagging very badly and did suffer from the "sporadic issues that may cause iPhone not to wake from sleep", which annoyed the hell out of me and at one stage was considering taking my iPhone to the Apple Store to get them to look at it. But now the 3.1.2 update has made my iPhone run so smoothly so i'm now stoked!

Sweeeeet my podcast are back in order again!!! Now I'm happy(doesn't take much to happy) god I'm a sad sack

the poster George (post #20) said that he can now Group MMS like you could with the previous carrier update before the 5.6(?) one came out like a week or two ago..,
unless i'm doing it wrong, i believe the Group MMS chat room thing is still turned off?
is anyone else getting Group Texting?

Hey guys
updated to 3.1.2 yesterday - battery issue still there
Every 1 min 1% goes down --- WTF -- I don't want to reset it as a new phone again coz have too much stuff in calendar
3.0 was awesome - it gave me 10 hour of usage in a single day -- yeah it used to be like that -- reall awesome
so looks like downgrading to 3.0 is the best bet as of now

I noticed something about the carrier update: If you look under Settings>General>Usage, the tethering data section is gone

Yes my effin battery is even worse. I started with 100% an hour ago and now I have 87%. I have sent a couple text and looked at FmLife for about 10 minutes. This is my second 3gs....................................Plus my mms works like azz. It has worked like azz since I got it...........................................I know the mms is ATT issue.

My friend put in an aftermarket battery in his 3g and it smokes................smokes in a good way. His battery life is great. I just don't want to open mine.

Did anybody have a problem with talking my phone when i would talk to somebody it would fade out then come back in then fade out again and come back in. it was a continous pattern??? It didn't do it the whole conversation.

I took my phone off the charger at 100% two hours later its at 85%, I only used it for 4 texts

I went from excellent wifi to spotty wifi on 3.1 to no (secure) wifi on 3.1.2. I can't connect to my own network unless I turn off all security. I've tried seemingly every combo and restart / reset - except a complete back-to-factory reset of my entire iPhone (scared of that one). Really frustrating...

All my issues seem to be resolved. MUCH better battery life, no more Coma Mode (so far). Thank you Apple!

By the way, after having SOOOOOOOOOO many problems with stated issues in 3.1 and did a complete "restore as new" a couple of weeks ago before doing the update this morning.

Battery Issues: I was having issues with my 3Gs. I had done a restore from my 3G. The battery life was all over the place. So after dealing with this since the 3Gs came out I was going to go to Apple Store. One of my good friends said try restoring the phone as new create as a new phone. I did not restore any of my old data. I have MobileMe and Exchange so all my contacts and calendars we saved. I manually removed my photos before the restore. Now I have not a single battery life issue. I go all day I have pushed turned on 24x7 for 4 accounts. At night I always leave my phone on. When I would get up in the moring maybe 6 hours later my battery life would go from say 80% to 20% and I would only have gotten 40 emails. (IT emails). Some times I would have to put on wall charger just to get the battery alive again. Still no issues and it has been 3 weeks since. Just for the sake of those who don't believe. I restored my old backup that I brought over from my 3G and the issues of the battery draining quickly started right back up... Something doesn't or didn't transfer over well. Our phones are software (oS) dependent. You wouldn't install your computer without formating your drive or writing over an old install if you wanted it to be reliable would you?

Follow up to over night part of my story.. Now I loose maybe 10 percent in the coarse of overnight and getting emails and text, and phone calls. Very much improved.

I don't have any of the listed issues. What I do have is out if order smart playlists. Where is the fix for that?

Updated to 3.1.2 this morning and now I'm having issues. Texting and making calls are a challenge. Sometimes they go through sometimes they don't, even with full bars.

After upgrade to 3.1.2 and the AT&T carrier update, suddenly my iPhone 3G is showing "3G" rather than "E" for its data network. We have never had 3G in Richmond, KY, strictly Edge network for data.
I ran Speedtest and selected 3G network; the results were 206 Kbits/s download and 31 Kbits/s upload in Richmond, KY. These speeds are more like our usual Edge network speeds. I wonder if the carrier update has goofed up the data network indicator or possibly AT&T really has turned up 3G here and has not turned up the bandwidth.
I suppose time will tell.

the carrier update takes tethering setting were you can see how much u have use tethering ..
its happening like mms once before with 3.0
they hide featurees

My battery sucks big time. I have done the restore as new before and it seems to help for a bit then i get crappy battery life again. It is too much of a hassle. I never had these issues updating before. You shouldn't have to go through all this. This is BULLS##T. I wish Apple would just do something right for once. They pride themselves on keep a tight check on their programming but this software f-ing sucks a$$.

does any1 no if tethering still available w/ 3.1.2? jus got new 3gs last week & got my tethering back cuz new phone preloaded w/ 3.0.1. would rather w/ internet tethering than mms.

Can someone please tell me if I never updated to 3.1 to behing with and then just heard about 3.1.2 coming out can I just update directly to 3.1.2 or what cause I connected my phone to iTunes and it said there's an uodate for my iPhone but it only said 3.1 without the 2. What's going on? Or do I have to get a text saying the update is available to me?

In reference to Peter's issue (post 108), I have the same wi-fi issue with the 3.1.2 update. Testing points to a problem with MAC address filtering. The iPhone MAC address seems to drop out from my router's 'Permission' list. When re assigned it works fine for a while and then drops out again.

update my 3GS to 3.1.2 , Did a clean restore . the update DID NOT fix the Coma and battery issue !
I can live with battery issue , but i can't live with a mobile phone that don't ring and accept calls and messages when it gos into Coma after sleep mode !
Love the iphone touch screen and i like the OS . But having a phone that don't tell you what happened ( calls - messages ) during the Coma is really serious problem !

I've had my iphone for a week. Within 3 hours of purchase, I came to know the infamous "coma mode". It happens within one minute of sleep mode on my iphone, UNLESS the iPod function is running, or when I have a particular application, alarmlite, running in the forground when I hit sleep.
This update did not fix anything for me. However, I am wondering if it is caused by the "Carrier Settings Update" or whatever it is, since after restore it seemed to be ok, but then when I synced it...back to coma-land.
Any idea how to uninstall carrier updates or the ramifications of doing so?

Not carrier settings. Turns out they install separately after a restore and the phone's still comatose. Will update them but I'm sure it won't fix it...though I'll let ya'll know if it do.

Fellas, Sorry to hear that you guys are having problems with your updates. I was getting a rash of crap from a couple of other boards (ATT Apple Forum and Apple Forum) for not putting my trust in 3.1.1 or even 3.1.2. They were telling me that just a few of the people were reporting any problems with their updates. I'm still running 3.0.1 with carrier file 5.5. I like every one else would like to see a more reliable OS. I'm now concerned that many of the developers will start using the 3.1.2. SDK to update all their apps. I sure hope Apple takes a close look at these website and takes action to investigate these problems.

MMS messages wouldn't send for me because I originally had an iphone 2g and upgraded to a 3gs...but it wasn't updated in at&t's system. (This is likely your issue)..I had to call at&t (dial 611 from a at&t phone) and let them know i wasn't able to send mms AND that it might because I upgraded from a 2g to a 3gs. They updated it in their systems, and I was able to send MMS messages after rebooting my phone.

Well, you should probably call from a different phone, cause I think they need your phone to be turned off while they do this...also, they may ask for your phone's IMEI number and Sim card number and such.

I tried to upgrade and it failed - Got Stuck. I then tried to Restore and followed apples' suggested steps. Still no dice. planning to take it to the apple store or to AT&T when I got my iPhone.

Iphone 3g here. This update is perfect and has improved my batery life very very mutch :)

The carrier update does get rid of Internet Tethering as an option. Just did it. Oh well. Back to carrying around the air card.

hey got problem with update 3.1.2 to my iPod touch it gets to 99% and its gonna install and it ways there is problem with my network or try again later and i have tried about 10 times and still does not work. so if anyone can help my would be very thankful

My voice command does not ask for confirmation before dialing a number, I have updated to 3.1.2 and it is still doing it. Do in need to enable this confirmation somewhere?

For all of you who are waiting for 3G Skyping, forget it. It will never happen. That would totally infringe on your service providers ability to make money. Apple would never allow voice over p2p social networks like Skype, it just won't happen.
(Wish it would though...)

Upgraded my iPod Touch with 3.1.2. Unfortunatelly it didn't fixed the crashes, the frequent "coma" nor the poor battery I have since upgrading to 3.1. For the first time in 25 years Apple has really dissapointed me. My (very expensive) 32G iPod Touch is useless.

I lost one of my calendars since upgrading to 3.1.2. Anyone else having this problem...only getting my work (exchange) calendar syncs

iPhone 3.1 update had re-created Microsoft Windows experiences-coma mode!
Hopefully I am back to Apple with 3.1.2

I have the same wifi issues as noted by Peter and Paul. I was not able to connect to my work or home wifi until I reconnected using WifiTrak. After doing that, my connection worked fine while the phone was active. When it went to sleep and came back, it showed Edge for a few minutes then picked up the wifi again.

Did the play count problem get resolved? My play count has been screwed up ever since I got the version 3 update.

If you still can't MMS call ATT tech support. My 3G phone was still "partially" registered with them as a 2G. They fixed this situation - made sure I was 3G across the board - and MMS has worked perfectly ever since.

Ipod touch brilliant idea well implemented, pity there is a mob of idiot control freaks in charge. lost me, next step android

In the camera a roll I have no pictures in the camera roll yet it stills show the number (1) in it. If I take a picture in the camera roll it show (2) in the camera roll when it only 1 picture in the camera roll. So when I delete the picture in the camera roll it shows at the time (0) pictures in the camera roll. But when I exit out of photos and return to photos the camera roll still show (1) in the camera roll I tried restoring my iPhone 3GS in iTunes but it still shows the same thing I've even tried rebooting my iPhone 3GS but still no changes. This is a but you must have missed so apple really needs to fix this bug to make it's iPhone 3GS correct and funcitional. All so make flash abode for iPhone 3GS this phone should work like an computer and also therething should be in iPhone 3GS for free without any other charges. I fell like if your paying over 100 dollars for a cellphone bill you should have everything I mean the full package. Thank you.

hi guys i was wondering if u guys are having the same problem as me. recently after the 3.1.2 update i had been having wifi issues with my iphone 3g. now it cant even detect a single wireless signal. i guess my conclusion this time round is "WTH!!!! APPLE JUST MURDERED MY WIFI!!!"

I have two iPhone 3G, 16gb with 3.1 and ATT 5.5 and I am having no issues with locking, wifi, or calls. HOWEVER... my wifes 8gb 3G which is on 3.1.2 with ATT 5.6 is a huge brick. She can make maybe one phone call before it freezes, requiring a restart. We usually get one or two bars in the house, but now the phone shows full bars, but won't connect a call or drops them within seconds of connecting. SApps are now causing it t olock up,tried to take picture and it locked up.
I have done a full reset and restore with NO success, but I did use the restore. After reading the threads I may do a factory reset and set it up as a new phone and see what happens.

Hi does anyone know how to fix sounds? My ringtone works but MSG tone does not :( no other sounds work on my phone at all Like lock sound etc and iPod does not work out side of headphones. All other sounds will work if my headphones are in! Thanks! X

I have a 3g iphone. Ever since the 3.1.2 update I am having a really hard time using the internet on the 3g network. It doesn't seem to be affecting calls or messaging, just safari-type things.
Every time I enter a URL, it fails to load, stating that the network isn't responding, about 80% of the time I'd say.
No problems on Wifi.
Anyone have any similar issues?

i have a 3g iphone. after i updated my firmware to 3.1.2 today, i was not able to sync my iphone with itunes. after i hit the sync button, nothing is happening. itunes is just backing up the data from the iphone & then it stops syncing.

ROB - Oh my gosh - the WiFiTrak tip worked. I've been at this for weeks. Ever since upgrading to 3.1.2 - no wifi connection. There are 14+ discussion boards with 700+ threads over on the apple.com site. No solutions. I called Apple Support today and they said it's not a known issue....Argh!

I need someone form the Sky or heaven help me regarding
“Unable to Load the Network list”
I have jailbreak 3g Iphone 3.1.2 firmware and I am not able to connect to network Receiving above error,
please please please pleaseplease please help me.

When I go to google.com a blank screen is shown, then when I'm playing a video suddenly it doesn't work: when I tap the iPod it doesn't respond so I have to go to the homescreen. YouTube . Com doesn't work on safari and on the app ocasionaly the video slows down while the audio keeps going.

I am super peeved about this peice of garbage.
I got the new update for five dollars$. Bought a bunch of apps/music around 45$
ipod touch was around 120.00$... I would rather had saved up for a fancy Mp3. I hate this garbage. Every time i get an app i have to turn it off hold the hold button wait for it to load. Then turn it back on. That also goes for music. Alsp everytime i time i use an app for it to save...
If i could, i would.return this crap. My brother had an ipod a few months back and it worked 99.9% perfect. Mine constantly breaksdown... Freezes... Loses money out of my account... And if it werent for the warrenty i would fricken throw this garbage in the trash
