Chronic Dev Team

Chronic Dev Team has finally released greenpois0n to jailbreak iOS 4.2.1 for iPhone 4, iPhone 3GS, iPhone 3G, iPod Touch 4G, iPod Touch 3G and iPad.

The jailbreak is untethered and doesn’t need iOS 4.2 beta 3 SHSH blobs to be saved like iPhone Dev Team’s Redsn0w 0.9.7, which is currently available for beta testing.

greenpois0n RC5 is currently available only for Mac users. p0sixninja of the Chronic Dev Team has mentioned that the Windows version will be released soon.

greenpois0n needs iOS 4.2.1 installed on your iOS device for it to work, so if you need to software unlock your iPhone then you should not upgrade to iOS 4.2.1.

greenpois0n for Mac supports the following iOS iDevices:

  • iPhone 4, iPhone 3GS, iPhone 3G
  • iPod Touch 4G, iPod Touch 3G
  • iPad

greenpois0n does not support hactivation, so your iPhone needs to be hactivated via iTunes.

Please note that jailbreaking your iDevice may void its warranty so proceed with caution and at your own risk. Please don’t forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone.

You can download greenpois0n for Mac from this link.

As always, please let us know how it goes.
