Frankly, the minute one ends unlimited for those grandfathers....the other will follow suit, imo.

With Verizon recently announcing that they are allowing their customers to upgrade and keep their unlimited, i am sure AT&T will do the same.

Come next year when the new iPhones come out, i am sure both companies will face the question again. At that time, I am suspect about whether they continue doing it. I suspect one will end the grandfathering and the other follows

So, which one? I am not sure it matters.
