Very promising iPhone 4S unlock coming soon

MuscleNerd recently posted on twitter that iPhone 4S unlock is in the works. He also mentioned that this is 4S only, not iPhone 4:

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

This is excellent news for iPhone 4S users, but will leave many iPhone 4 owners disappointed.
