It’s been quite a long time for iPhone 4S in the market but we haven’t seen any unlock or Jailbreak from the Hackers on iPhone 4S running iOS 5. Now according to iPhone Dev Team member Musclenerd confirmed that they have found a way to unlock iPhone 4S on any carrier.
Crazy Thanksgiving weekend! Very promising 4S unlock (twitpic.com/7kku4t) is in the works (Not i4, just 4S..that’s crazy part)
The unlock will only work on iPhone 4S and not on iPhone 4 (latest baseband).The unlock might have some links with the A5 processor of iPhone 4S that’s why it will only work on iPhone 4S.
It’s in progress so iPhone Dev Team might release it in near future. Stay tuned!
