I'm probably going to buy a mini, but don't know if I should buy AT&T or Verizon. Is there any information on the data plans for them? Also, I have no one around here that has an LTE phone to ask which one is better and I'm suspicious of the maps-- Verizon's seems to show LTE in my spot, but AT&T doesn't. Any thoughts on any of this? I want to pre-order on opening day, but want to buy the right device. Thanks.
