GeoHot is back Untethered Jailbreak video for iPhone, iPod Touch & iPad
According to him
The jailbreak is all software based, and is as simple to use as blackra1n. It is completely untethered, works on all current tethered models(ipt2, 3gs, ipt3), and will probably work on iPad too.
Don't ask about a release date. You won't make it happen any sooner
