I use AT&T and I have an HTC but it isn't a smart phone. So if I cut the SIM card into a nano SIM card, which is used for iPhones, and put it in an iPhone 4S, will the phone work? Also I do not use data on my phone, only texting and calling and I'm not telling the AT&T people because they would make me get an iPhone which I can't do until my contract ends next year or ill have to pay 300 dollars.
