Okay here is the background. I have been with ATT for 5 years now. I still use my SIM from WAY back in the day, even before 3G came out. Obviously you all can conclude that I do not use data plan of any sort. I have the new iPhone 4, and still plan on not using a data plan if i can avoid it. So there are 2 questions I have: If i were to cut up my ATT NON 3G sim card to microsim size, would I be able to use it in the iPhone 4? Or would I still have to go with the unlock route if i were to do that? I have not been able to find solid facts about this whether it will work or not (I mean, i AM on ATT after all, so theoretically i needn't unlock but I assume the card not being 3G may pose problems) Second option: Go on over to ATT and request a micro sim. Would they say no because I am not on an "official" iPhone plan? Thanks all.
