AT&T Limits on FaceTime Raise Net Neutrality Questions

When Apple releases its next version of its mobile operating system iOS this fall, iPhone customers will have the option to place FaceTime video calls over the cellular network, whereas before they could do so only on Wi-Fi. On the AT&T network, however, that privilege will be available to customers only on a certain type of data plan, which has raised debate on whether or not the carrier is violating government rules.
