Official Ultrasn0w Fix (v1.2.1) to Unlock iOS 4.3.1 Releasing Tonight!

MuscleNerd (@MuscleNerd), who happens to be one of the most vocal members of iPhone Dev-Team just confirmed that official Ultrasn0w 1.2.1 update to unlock iPhone 4 and iPhone 3GS on iOS 4.3.1 will be releasing tonight. For those who don't know, Ultrasn0w 1.2 was unable to unlock any iPhone on iOS 4.3.1 due to ASLR security feature which broke ultrasn0w code naively using 0x1000 as the main executable base address.

So the upcoming Ultrasn0w 1.2.1 will be mandatory for all those iPhone users who are jailbroken on iOS 4.3.1 with older basebands. It does not matter if they rely on a locked or unlocked iDevice as signal-bars issue is experienced by all iPhone users on iOS 4.3.1 with older basebands.
