I have had nothing but good experiences with Cingular. I can even get a strong signal on base where others have trouble. We also have no land line, mostly because we call home so often, it is cheaper using the cell. I haven't had any bad experiences with dropped calls, and their customer service has always been good so far. We've had them for two years and just resigned our contracts.
Also, we had Verizon before Cingular, and it was a nightmare. Can you hear me now my a$$.
