Mark Collins, SVP of Data and Voice Products at AT&T:
"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."
As an iPhone 4S owner, I couldn't be more excited. It's about time AT&T did a good thing when it comes to their network.
Update: As noted by reader Jay Torres, this new rule doesn't apply to people still using their grandfathered unlimited plans from the old iPhone days. Didn't catch that on my first read-through of AT&T's blog post, so thanks to Jay for pointing it out to me.
