Well, today one og Cingular's "Parent" company's signed a 800 line account wth the potential to add 2500 more. Now, I don't have a PhD in rocket science but why would they do that? Verizon is the only Cell phone company that could go out of business today in a profit margin. They spend 4billion dollars a yr into their network. 100,000 test calls a month. Yeah they have there problems to but are nationally know to be the best from the rest. By the way, SBC is a landline based company in California who signed that contract. to all Cingular and At&t customers doesn't this make you wonder if they can't keep their own. To ansewer the question for you, It's Verizon, not cingular.
