We haven’t seen any leaks or heard any rumors about what the next Un-carrier Amped move might be, so for now tomorrow’s announcement is a mystery. We do know that Un-carrier Amped is all about amping up previous Un-carrier announcements, and we’ve already seen JUMP! and Simple Choice get amped, so we can eliminate those two.

What Un-carrier move do you think T-Mo is going amp up next?
