Will AT&T Charge Users of FaceTime?

AT&T appears to be testing a method to charge Apple FaceTime users when they use mobile network bandwidth, 9to5mac.com reports. There is no charge when users are on Wi-Fi networks.

Of course, in some cases that will add value for end users. Nor, it should be noted, is such charging a formal violation of existing network neutrality rules, which apply only to fixed network broadband access.
