I have an Nokia phone and I use ATT/Cingular. I want to get a new phone but I'm not really liking any of the models available. There are some neat Samsung ones that I want but they say they're for T-Mobile. The rep. at the store said that the phone only needed to support GSM in order to work on the ATT network. I was wondering if I could just purchase one of these phones off the internet and pop in my SIM card and it'd work?
