In this video, I show you how to jailbreak your iphone 3g using quickpwn. (These steps will work for the iphone, iphone 3g, and the original ipod touch.) By the way, this program, which is free, will work on both Windows and MAC OS X.

All you need is itunes 8.0, a supported device (above) flashed with software 2.1 and the software quickpwn from http://blog.iphone-dev.org/

The steps are really easy and you should be up and running in less than 10 minutes. And if you want to go back to the original software, all you have to do is restore it through itunes.
