AT&T to enable FaceTime over Cellular for all iOS devices at no extra charge

AT&T (T) says on its blog "As a result of ongoing testing, we’re announcing AT&T will enable FaceTime over Cellular at no extra charge for customers with any tiered data plan using a compatible iOS device. This means iPhone 4S customers with tiered plans will be able to make FaceTime calls over the AT&T cellular network. AT&T previously made FaceTime over Cellular available to customers with a Mobile Share plan and those with an LTE device on tiered plans."
