Greenpois0n Updated, Now Supports Verizon iPhone Jailbreak Tom February 8, 2011 Technology The Greenpois0n jailbreaking tool for iOS devices has been updated to support the latest iPhone 4 on Verizon. For those of you unfamiliar with Greenpois0n it’s a jailbreaking app for Windows/PC/Linux that provides an untethered (don’t need to have the phone attached to the computer to boot up) jailbreak for most iOS devices on 4.2.1. The current release of the software does not support the Apple TV 2 with the latest firmware untethered, but they promise that it will be included in RC6 when it’s released. So for all you Verizon iPhone users that want to join the jailbreak club, head on over to Greenpois0n.com and get cracking! Update (2/13/11): Green Pois0n was updated again and now supports untethered jailbreaking of the Apple TV 2G as well as fixes a few issues that RC5 had.
