We've had Sprint for the last several years, but have been fairly dissatisfied with their service. A couple of weeks ago we switched to Cingular, which I've heard great things about, but we've had nothing with trouble with the service: Dropped calls, calls not going through at all, fading in and out while talking on it. I'm kind of at my wit's end. I guess the other two big choices are Verizon and T-Mobile. I'd appreciate any advice on which service you have and whether or not you're satisfied with it.
