greenpois0n Jailbreak For Windows Released! (update: added tutorial link)

Finally! After all that drama in the jailbreak scene with geohot’s limera1n, we have some good news. The Chronic Dev Team has released their highly anticipated jailbreak for iOS devices. First off, compatibility. From The Chronic Dev Team:

“Initially, this will be a Windows-only release. This is due to some technical complications that we soon hope to correct. We apologize for any inconvenience.”

“This release of greenpois0n supports:
– iPhone 4
– iPhone 3G S
– iPod touch (4th Generation)
– iPod touch (3rd Generation)
– iPad”

“Soon there will be another release, adding things like support for:
– Apple TV (2nd Generation)
– iPod touch (2nd Generation)”

“Don’t forget to upgrade to 4.1 (iphone/ipod) or 3.2.2 (ipad) before starting greenpois0n. If you need unlock, use tinyumbrella to keep old baseband.”

If you have an iPhone 3G or iPod Touch (2nd Generation), use redsn0w (Mac, Windows).

Regarding the unlock (ultrasn0w), you will lose your unlock and your ability to unlock (possibly forever) if you update or restore your iPhone through iTunes. There is one exception. If you have an iPhone 4, you can use TinyUmbrella to save your SHSH, update to 4.1 and jailbreak without upgrading your baseband and therefore keeping your unlock. I’ve posted how to links from iClarified right below in our source. This ONLY works with the iPhone 4, if you have an iPhone 3G/3GS, wait for PwnageTool. If you rely on your unlock or want the safest possible way to upgrade without losing your unlock, wait for PwnageTool.

As for anyone with a factory unlocked iPhone 4 (like me!), feel free to update through iTunes and jailbreak with greenpois0n as your unlock is not dependant on software.

For the technical bunch: limera1n initially used a beta version of @comex’s untethered exploit which is what made it unstable. There have been numerous updates to it but some users are still experiencing issues. As for SHAtter, that bootrom exploit has not been used in the greenpois0n release and remains safe (as far as we know) from Apple. This is great news.

As always with jailbreaks, proceed with caution. This is the jailbreak you are looking for. I will try to answer any questions you have. Share your experience in our comments!

Update: iClarified has now put up a step by step tutorial for jailbreaking your iPhone 4/3GS with greenpois0n, I’ve added it to our source links below.
