I already have an ATT phone and i went to my local ATT store and the guy said that i could go on ebay or something like that, buy the phone and put my sim card in it, but all the phones that i find are way to expencive, they are less in the store!! so is there anyplace i can buy one online cheap without signing up for a plan. (The reason i don't buy one in the store is because my contract isn't up yet)
