AT&T Expanding FaceTime Over Cellular Access
Submitted by Frank Macey on
FaceTime users with the iPhone 4S rejoice. You won't have to upgrade to the LTE iPhone 5 in order to use the service with an AT&T tiered data plan. Over the next few months, the carrier is rolling out cellular FaceTime access to everyone with a compatible device, except for those with grandfathered unlimited data plans.

Previously, FaceTime over cellular was only available to iOS devices with LTE, including the iPhone 5, third and fourth generation iPads, and the iPad mini. AT&T explains they have completed testing on their networks to ensure that providing this added service will not adversely affect subscribers.
