Wondering if anyone has had issues putting a Blackberry SIM card in an iPhone? I swapped mine this morning from a T-Mobile Blackberry 8700. The phone worked, but data did not. When I swapped them back, the SIM stopped working. I realized that the SIM was in upside down, so I think I may have messed it up that way. I got T-Mobile to give me a new SIM, but I'm leery to stick the new one in and mess it up to. Any experiences?
