Well when this story first broke that AT&T was not going to allow anyone to use FaceTime unless you had a shard mobile plan, you can imagine how many folks got pissed. Well it seems like the boys had a change of heart.
They are announcing that all iPhone 5 users will be able to use Facetime over the carriers LTE network even if they do not have a shared data plan. So no extra fees.
expect AT&T to roll out this function over the 8-10 weeks.
