Alright Folks! if you have a 3GS iPhone and have been waiting for the Jailbreak on firmware 3.1, there is some good news for you guys. The iPhone Dev-Team has successfully completed an upgrade of a jailbroken iPhone 3GS from 3.0 to 3.1 without losing the jailbreak itself !

This in short means that we soon will see an update to the PwnageTool which will add probably add support for creating a custom ipsw that can then be used to upgrade the iPhone 3GS.
