So I used to have AT&T back in the day with an original iPhone. After a hiatus with Verizon I've come back for the BlackBerry torch, however I'm stuck in the 2GB plan. I've read that there's a way to get unlimited back by switching back and forth between phones. Here's what I have: 1) Original iPhone that's currently used as an alarm clock 2) A sim that shows as "Sim not provisioned" when put into my blackberry. It's my old one from when I had AT&T. Would I be able to do this shenanigans without dealing with going into an AT&T store? I'm pretty sure they'd know I was up to something since I've made multiple visits there in the past.
