have an LTE enabled device with a tiered data plan. So that means the third-generation Apple iPad, the Apple iPhone 5, the Apple iPad mini and the fourth iteration of the Apple iPad are the devices you must have to use Face Time over cellular without a Mobile Share plan on the nation's second largest carrier.
For AT&T, there will be no more talk that the carrier would be investigated by the FCC for violating net neutrality rules, and it puts the mobile operator a little closer to being on an equal footing with Verizon and Sprint. Which leads us to the obvious conclusion that those AT&T customers with the Apple iPhone 4 and iPhone 4S who want FaceTime over cellular will have to either upgrade to the Apple iPhone 5, or switch carriers. AT&T must feel confident that these subscribers will go for the upgrade.
