Chronic Dev Releases GreenPois0n RC5 Jailbreak
February 4, 2011
Chronic Dev has just released its long awaited GreenPois0n RC5. It brings full untethered iOS 4.2.1 jailbreak access across all devices.
The jailbreak is available now for the Mac. A Windows version is expected in the next week or two. The developer hurried the release since it has been patched in iOS 4.3.
Unlike Redsn0w 0.9.7, GreenPois0n RC5 does not require SHSH blobs of 4.2b3 saved on Cydia. You can jailbreak any iOS device out of the box on iOS 4.2.1 using this latest version of GreenPois0n.
Visit the GreenPois0n site to download the jailbreak or for more information.
Update: If you're having trouble obtaining the right file at the moment (RC5), you can find a mirrored copy here.
