greenpois0n

Greenpois0n is a name shared by a series of iOS jailbreaking tools developed by Chronic Dev Team (sometimes called the Greenpois0n team) that use exploits to remove software restrictions on iPhones, iPads, iPod touches, and Apple TVs. Greenpois0n's initial release in October 2010 jailbroke iOS 4.1, and its second version in February 2011 jailbroke iOS 4.2.1 as well as iOS 4.2.6 on CDMA iPhones. The second generation of the tool, Greenpois0n Absinthe, was developed with iPhone Dev Team members and jailbroke iOS 5.0.1 in January 2012 (providing the first jailbreak of the iPhone 4S), and a second version jailbroke iOS 5.1.1 in May 2012 (providing the first jailbreak of the third generation iPad).Jailbreaking enables root access to the iOS operating system, allowing the installation of applications and customizations that are unavailable through the official App Store for iOS. Jailbreaking voids the device's warranty, and Apple releases iOS updates to make jailbreaking more difficult.
