Ultrasn0w to unlock iPhone 4S on iOS 5 / 5.0.1 dropping soon ? Today MuscleNerd, the iPhone Dev-Team's spokesman has announced some interesting news on his Twitter account. MuscleNerd confirmed that the Dev-team has achieved significant progress on iPhone 4S unlock.
MuscleNerd: Crazy Thanksgiving weekend! Very promising 4S unlock (http://twitpic.com/7kku4t) is in the works (Not i4, just 4S..that's crazy part)Unfortunately, this hack will be able to unlock iPhone 4S only as it is not compatible with iPhone 4. So we are expecting that MuscleNerd will update ultrasn0w to be able to unlock iPhone 4S. The amazing news that we read between lines that there is no unlock without jailbreak (Cydia). So do you expect that MuscleNerd will release iPhone 4S jailbreak by Christmas ?
Update: Now you can make iPhone official factory unlock, you can check the details from here
