I know AT&T's enabling FaceTime over 3G/"4G"/ceullular for all customers. I myself noticed the updated setting a few days ago. (Finally!) However I just installed iOS 6.1. And I just saw in the cellular settings that FaceTime is disabled and when I try to turn it on it shows the same pop-up about calling AT&T. Anyone else notice that? Or is 3G FaceTime just spotty for the next couple weeks?
Bump. Anyone else notice this? If it matters it gave me a pop-up after installing 6.1 about it changing caller ID and using the new @icloud.com email address. (And AT&T didn't know anything about it, in fact they were a little surprised I even had cellular FaceTime at all already.)
