The Info:

The other day the iPhone dev team released redsn0w version 0.7 for the Mac. Redsn0w is a program that was originally created to overcome the change in the iTouch 2g’s hardware that prevented the QuckPwn or PwnageTool from being able to jailbreak the iTouch 2g. The dev team has now taken this amazing tool and made it work on the iPhone 2G, iPhone 3G, iTouch 1g, and iTouch 2g and it can even unlock the iPhone 2G! They’ve also given it a GUI (previously, it was a command line only tool). Follow the direction below to jailbreak all four iDevices (the iPhone 3GS isn’t supported… Yet) and unlock the iPhone 2G.
