Chronic Dev Team has just released Greenpois0n to jailbreak iOS 4.1 for iPhone 4, iPhone 3GS, iPod Touch 4G, iPod Touch 3G and iOS 3.2.2 for iPad. Chronic Dev team delayed the release of Greenpois0n as they have used the same USB bootrom exploit used in Limerain instead of using SHAtter exploit to preserve it for the future.


Greenpois0n works only on iOS 4.1 and iOS 3.2.2 for iPad. iPhone 4 users can use Tiny Umbrella if they want to upgrade to iOS 4.1 to preserve the baseband so that they can unlock it using Ultrasn0w after jailbreaking their iPhone.

Note : If you want to unlock your iPhone 3GS then do NOT upgrade to iOS 4.1. Dev Team will be releasing PwnageTool that will preserve the baseband while updating the iPhone to iOS 4.1.

Greenpois0n supports the following iDevices:

* iPhone 4
* iPhone 3GS
* iPod Touch 4G
* iPod Touch 3G
* iPad

Greenpois0n is currently available only for Windows users. Mac version will be released soon.

Note : There is a Mac button on the Greenpois0n website, but it’s not functional.

Jailbreak your iDevices running iOS 4.1 using Greenpois0n (tutorial here).
