Dev Team frontman and unlock guru MuscleNerd has given an update on a new unlock for the newly-released iPhone 4S. According to MuscleNerd, a "very promising" unlock for the new handset is "in the works."
While iPhone 3GS and iPhone 4 owners with older basebands have been able to unlock after jailbreaking for awhile now, there's a whole set of newer basebands waiting for an UltraSn0w update.
