After the sudden surprise from GeoHot with Limera1n, the Chronic Dev team has finally released the Greenpois0n tool to jailbreak iOS 4.1. Greenpois0n Jailbreak tool is currently available for Windows, Linux and Mac. Greenpois0n Jailbreak Tool can jailbreak iOS 4.1 on iPhone 4, iPhone 3GS, iPod Touch 4G, iPod Touch 3G and iOS 3.2.2 on iPad. Greenpois0n tool that was planned to be released earlier was expected to use the SHAtter BootROM exploit, but the current release of greenpois0n tool uses the GeoHot’s exploit that was used in Limera1n. The Chronic Dev Team preserved the SHAtter exploit to use it in the next version of greenpois0n that can be used to jailbreak iOS 4.2. BTW if you rely on iPhone Unlock then better stay away with this jailbreak.
