Well, I believed Storm 2 was unlocked, but when I called Verizon, I was given a whole long step-by-step procedure on how to to unlock it and be able to accept a third-party GSM SIM. I didn't have a need and chance to do this yet, but, still, what gives?
just tried this with my old verizon sim card and it is not working. i tried it in different modes but none of them worked. it is possible that verizon deactivated this sim card when i switched from phones from blackberry to rezound, since active t-mobile sim card was working fine. i'm waiting for some input from people with more technical knowledge than mine)
