UltraSn0w now fully supports IOS 5.1

UltraSn0w has finally been updated to 2.7.  The good news is it Supports IOS 5.1 (and 5.1.1), so UltraSn0w Fixer is no longer needed.  The bad news is there's no changes in baseband support, so people waiting for 4.11.08 and 4.12.01 unlocks on the iPhone 4 are still without a solution, other than getting an IMEI unlock from their carrier.



Here's an updated chart of Basebands and their unlockable status.
