My cellphone is wrecked, so I need to get a new one. I would like to get an iPhone, but I really don't want to pay an extra $20 a month for the data plan. Is it possible to just buy an iPhone from the Apple store and just insert my current SIM card into it? Will that get me around the data plan? Will it even work? I've heard of people hacking their phones, but I still use AT&T. I just want an iPhone with my current contract and no data plan. If you can offer any suggestions or help, I would really appreciate it.
