If you’ve got your hands on the new iPhone, the iPhone 3GS and wondering when will you be able to unlock or jailbreak your device then don’t worry. Because just couple days after the release of iPhone 3GS Dev team has released it’s unlock. Here’s what they had to say about the ultrasn0w unlock for iPhone 3GS.

Our ultrasn0w program uses the at+xlog crash as an injection vector of our unlocking payload — and it does so on the 3GS in exactly the same way as on the 3G!  But this injection vector will be lost if you update to 3.1 using the official Apple IPSW, which updates the baseband.  So stay away from official 3.1 IPSWs until we release the tools that let you update the firmware without updating the baseband.
