Sorry to do this. But DC-area residents, a question. Are we hating Cingular? I used it before and don't remember the coverage being so terrible, but online the complaining is pretty voiciferous. And yes, the customer service was abysmal. But my family all uses it and the free in-network deal is nice. But is it so bad I should avoid? And how is T-mobile? I hear their customer service is great but how is DC coverage?
