AT&T will Block Facetime/3G to non Shared Data Plan Customers

AT&T goes for a more complex application and subscriber-based policy framework.
 
The carrier issued a statement (below) denying it will surcharge Apple's Facetime over 3G (planned for iOS6), but will provide it only to its shared data plans customers. Other customers will be able to use Facetime over Wi-Fi only.

"AT&T will offer FaceTime over Cellular as an added benefit of our new Mobile Share data plans, which were created to meet customers’ growing data needs at a great value. With Mobile Share, the more data you use, the more you save. FaceTime will continue to be available over Wi-Fi for all our customers".
