I have already decided on Cingular for a carrier since it is the only thing that gets good reception at my house. I am looking at a Motorola MPx220 flip phone. I've never had a cell phone before and don't know how the purchasing and programming of the phone works. Buy.com has the phone free with a new service plan but I don't know how to get those rebates if I sign up for a plan locally. Do I need to just hope that the store that I go to has the phone I want or how does all this work?
