iPhone 4S Unlock in Progress and ‘Very Promising’ According to Dev Team

Muscle Nerd from the iPhone Dev Team sent out an interesting tweet this morning in regards to the iPhone 4S unlock.

Crazy Thanksgiving weekend! Very promising 4S unlock (http://twitpic.com/7kku4t) is in the works (Not i4, just 4S..that’s crazy part)

He mentions progress is coming along for the iPhone 4S only via ultrasn0w. Only iPhone 4 users with the baseband 01.59.00 can unlock their phones at this moment.

As for iPhone 3G and 3GS users, only the following basebands can be unlocked: 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00.

It seems every time there’s a long weekend or holiday the iPhone Dev Team discovers a new exploit somehow. Last Thanksgiving, they unveiled news about the iOS 4.2.1 untethered jailbreak via an updated release of redsn0w. Maybe turkey dinners are the secret to discovering iPhone and iOS exploits?
