Version 2 Of Jailbreak Software Released, Supports All Current Devices
George Hotz has released release candidate 2 (RC2) of Blackra1n, his one-click software tool for jailbreaking all iPhones and iPod touches. Currently, the latest models of iPhone must be tethered to Blackra1n to boot correctly or the jailbreak data is wiped, but otherwise it still works just as well as on other devices.
It should be noted that this tool is for jailbreaking only, and will not unlock the device for use on other carriers.
You can get Blackra1n for Windows or Mac at Blackra1n.com
