AT&T might charge for FaceTime over Cellular
Wasn't it a delight when Apple announced that FaceTime will finally work over 3G/4G connections? That would be possible on an iPhone 4S, a new iPad, and future models of these devices once iOS 6 is out. Unfortunately, it seems like some carriers will be charging for the feature, or at least AT&T intends to, judging by evidence found in a beta version of iOS 6.
Upon attempting to enable FaceTime over Cellular, the user is instructed to contact AT&T in order to activate the feature. You know, just like AT&T users are required to pay an additional fee should they want their iPhone to work as a Wi-Fi hotspot.
Interestingly, the folks tried to enable FaceTime over Cellular on a Verizon iPad and it worked just fine, without requiring a subscription of any kind. However, that does not necessarily mean that the carrier won't add a fee at a later time.
So far, we don't know anything as to how much AT&T will charge its users for FaceTime over 3G/4G. We should get more information on the matter by the time iOS 6 is released.
