George Hotz or better known to us as Geohot has hit back again by making untethered jailbreak a reality. He has not given the tool any name but it has been announced. You will be able to Jailbreak your iPhone 3Gs, iPod touch 2G and 3G (2nd and 3rd Generation) and the Jailbreak will not be tethered meaning that you do not have to Jailbreak every time you do hard reboot.

Now you can do untethered Jailbreak of your iPhone 3G/3Gs running latest firmware 3.1.3 with "Spirit".

The release date has not yet been specified but @geohot has posted a demonstration video which shows a Jailbroken iPod touch (probably 3G). It’s turned off (hard reboot) and then when it turns on it does not ask to “Connect to iTunes” window, rather it works just like before!

Note: Geohot suspects that this Jailbreak might also work on iPad!
