UPDATED: Greenpois0n iOS 4.1 Jailbreak announced! [Jailbreak]

Moments ago, prominent Chronic Dev Team member Joshua Hill (p0sixninja) announced via twitter that "Things have progressed to the point where we don't expect anymore roadblocks. ETA for greenpois0n is 10/10/10 at 10:10:10AM." This hotly anticipated Jailbreak should bring another large contingent into the Jailbreaking community as many new iPhone users who have not been able to jailbreak 4.0.2 and 4.1 will now be able to jailbreak their device.

While details of the jailbreak, such as whether it will be tethered or how it will be implemented have not been announced, that information will likely be given shortly... As a reminder, it is a good idea to save your SHSH blobs with TinyUmbrella if you have not already done so.

UPDATE: Greenpois0n is based on the SHAtter exploit which only works on 4th generation (2010) devices such as iPhone 4, iPad, and the iPod Touch 4. Older devices such as the iPhone 3GS will not be able to use Greenpois0n. Also if you wish to retain your ultrasn0w unlock, you will have to restore to a custom iPSW with baseband 01.59.00 and not the official apple 4.1 since baseband firmware CANNOT be downgraded.

Is Farbod on the team now?

Steven c says:

It's whether not weather. But spelling and grammar aside, I'm stoked


HELL effing YEAH! So PUMPED!!! Greenpois0n is so fly like a G6!

@chiratsu says:

well this is exciting! I don't believe they will wait till Sunday. I expect the JB to drop sooner ;)

jodiz1 says:

What is a SHSH blob? An how do you save them?

matthew23 says:

Why wouldn't they wait until 10/10/10 like he says? Gives them a day or two more to finalize everything and then drop it like binary code! 101010101010

Farbod21 says:

Jz, click on the TinyUmbrella Tutorial at the bottom...

Chris says:

They are releasing it on 42 day! (from the hitchhikers guide to the galaxy). 101010 is 42 in binary.

DoubleDown says:

@ Matthew, that's perfect !

Michael says:

@Pete - You can jailbreak the iPad already. It's dead simple.

pain says:

will it be able to jailbreak ipod touches 3g firmware 4.1??

Ridikuloust says:

Great.can't wait so I can use chatr again

chazzyfie says:

yaaa but will we be able to unlock it though =[

Farbod21 says:

Just a reminder, greenpois0n is ONLY for 4th gen devices, so ipad, iP4, and iPT4G. Also if you want unlock you will have to restore to custom IPSW that has BB 01.59.00

Tazzy says:

@Micheal What do u mean theirs a jailbreak for iPad if so where can I find the info to do it at!?! I have 3.2.2!!!

Farbod21 says:

Tazzy, it will be released at the same time, as it will be the same jailbreak for all three devices... Stay tuned

nickpthemft says:

Quick question(s) - iPhone 4 + jailbroken iOS 4.0.1...any need for greenpois0n, or can I just do as some of the scuttlebutt is suggesting and install a jailbroken iOS 4.1 ipsw on it without the need for a jailbreak?
Also, is this going to be a tethered jailbreak? Originally it was discussed to be so, but now I'm hearing mutterings that it'll be untethered...any confirmation one way or the other?

Tazzy says:

Thanks Farbod21!!!!

Farbod21 says:

Nick, you cant install a JB ipsw. You can only install a custom ipsw that has an older BB firmware and then JB that. If you want 4.1 its worth it, otherwise, its not. As for tethered, they havent said one way or the other yet.
Salami, its GMT.

Farbod21 says:

NOTICE: If you want to unlock, DO NOT upgrade to 4.1 until you get a custom IPSW that includes an unlockable baseband, or else you might never be able to unlock your phone... Just sayin.

Buffdaddydeluxe says:

Chpwn stated 4.1 will never be unlocked!

mattw says:

@Michael, yes where is this JB for iPad 3.2.2?

Farbod21 says:

Never say never, but yeah, as of right now, BB 01.59.00 is the only confirmed unlock, so you never want to take chances.
The Devs are really keeping things under wraps, so as for the ipad and other questions, I will update as soon as I can confirm info. I dont want to speculate...

v1nn1e says:

Awesome news!
I asked this question a while back (prematurely) but nobody really knew an answer. So, since this JB is a hardware exploit (not software), what happens if you need to swap out your iWhatever? Jailbreaking voids your warranty, and your Genius Bar friend (unless they are an actual bar friend) will shoot you the super stink eye and deny any request for a swap.
So, will the JB be un-jailbreakable in that case? It's probably something to think about before pulling the trigger?

Farbod21 says:

Vince, I dont want to speculate before we know how the payload will be delivered but its my guess that you will be able to un-JB and re-JB much like the star JB. There are still a lot of questions to be answered, but at least now we know we will get them soon...

v1nn1e says:

Word. I'm still excited, haha. :)

iphone4idiots says:

OK, from what I've read the big points are
1) SHAtter and greenpoison are only possible on the fourth-gen devices: iPad, iPhone 4, and iPod touch 4G. These all use the A4 chip.
2) If you update to 4.1 using Tiny Umbrella and then jb with Greenp0ison you'll be able to unlock. If you're already on 4.1 your stuck until (if) a new unlock is developed. Or put another way, if you wish to retain your ultrasn0w unlock, you will have to restore to a custom iPSW with baseband 01.59.00 and not the official apple 4.1 since baseband firmware CANNOT be downgraded.
This is great news for iPhone 4 people like me. The proximity sensor is such a pain, but it wasn't worth going to 4.1 to fix since it would have cost me the jailbreak. Now I can finally get rid of the iPhone 4's biggest problem. Antennagate was a non issue - the proximity sensor is a problem, but one I'll only have to live with for 3 more days :) Oh, and I'll finally get Game Center on this device.

Farbod21 says:

Yeah, Semaphore confirmed that you can use TU to upgrade to 4.1 without upgrading your baseband... But wait until all the details of Greenpois0n are released before I did anything other than saving your SHSH blobs...

keith Ceasar says:

The latest firmware for Ipad is 3.2.2 where is the jailbreak for that? Will the Ipad be jb

iphone4idiots says:

@keith Ceasar
This should jb 3.2.2

Farbod21 says:

Greenpois0n will be released as 4.1 (iP4 and iPT4) and 3.2.2 (iPad) and it will be untethered. It looks like you will have to both hook it up to your computer and use userland "assistance" to activate the jailbreak and keep it untethered. This exact process should be explained up soon...

Boots says:

Sooooo what do 3gs and older users use???

iphone4idiots says:

Cry, be patient or upgrade to iPhone 4.

beanboy says:

I'm a little confused... I have an iPhone 4 with 4.02 not activated and I need to unlock. Can I just go ahead and upgrade to 4.1 and then jailbreak and ultrasn0w? or do I have to do the TinyUmbrella thing? Moreover, will ultrasn0w run on the 4.1 JB? Thanks to anyone for the input!

Farbod21 says:

Beanboy, if you upgrade to 4.1 you will not be able to unlock for the foreseeable future. Wait until greenpois0n is released and all details should be explained...

Eagleyesmith says:

Can't wait to upgrade and then jailbreak. But this is one jailbreak where I'm going to miss Rock. The "Restore from Backup" feature is was so nice and easy.

samus512 says:

wow lol finally a release date....... 101010? is that something special? lol 2730? they shouldve just given it to us todayyyy.

HT says:

what about 3gs 4.1 bb 05.14.02 users? what can these be jb'ed with if greenpois0n is not compatible with these?

Brayden says:

Will it work on 2g ipod touches?

Jordan says:

no only on 4th gen devices

Bev says:

Why don't people read before they post. The same question is being answered over and over.

v1nn1e says:

What part of "Greenpois0n is based on the SHAtter exploit which only works on 4th generation (2010) devices such as iPhone 4, iPad, and the iPod Touch 4. Older devices such as the iPhone 3GS will not be able to use Greenpois0n" was so un-clear? Hello?

Dennis says:

To everyone asking if this will work with older devices:
Greenpois0n and SHAtter only work for devices with the A4 chip (ip4, ipt4, ipad) but redsnow 0.9.6 works for most other devices. Use that to jailbreak 4.1 instead.

Dennis says:

^ I'm sorry, I mean redsn0w 0.9.6 and sn0wbreeze 2.0.2 will work for all devices (some devices require certain conditions to be met before jailbreaking). For full details see http://en.wikipedia.org/wiki/IOSjailbreaking#Current.283.2.1-4.1.29

Farbod21 says:

Everyone needs to save their SHSH blobs. Even if you dont JB, still save them. You never know when it might come in handy.

Brayden says:

Thought so :( I was just wandering cause I accidentally download 4.1 and installed it insted of 4.0 , damn that's gay :( any news of a 4.1 jailbreak yet?

Rapscallion says:

@Brayden "any news of a 4.1 jailbreak yet?"
Ummmm... did you read the article?

Kafer says:

So anybody knows what will happen with iPhone 3GS with 4.0.2 and 4.1?
Is going to be an alternate Jailbrake from GreenPois0n?
FW 4.0.2 is my case and I want to Jailbrake my iPhone 3GS ASAP!
If you know how please share your comments.

Luis says:

Omg so' many idiotas. Cant they do a 10minutes Google? Ull get all the answers there. Not here

Kafer says:

Luis, That is why this is an IPhone blog.
I expect to find the answers and updates faster in this site and avoid to stay as an idiota searching the Internet for answers.
Some of us have real life.
