Greenpois0n Untethered Jailbreak for iOS 4.2.1 Released
After a long wait, Chronic Dev Team finally released a latest version GreenPois0n RC5 of their untethered jailbreak for iOS 4.2.1 for all iOS devices. Until now, we only had the beta or tethered version of the iPhone Dev Team’s redsn0w tool to jailbreak iPads and iPhones running iOS 4.2.1, however this Chronic Dev Team has come up with the first stable version greenpois0n, which is available for fully untethered jailbreak. This one is compatible with iPad, iPhone 3GS, and fourth generation iPhone and iPod touch running iOS 4.2.1. However, note that greenpois0n is available for Mac only and Windows & linux version is yet to arrive.
