sprint vs cingular

I have sprint. It seems to have service in a lot of locations, mountains etc. Sometime's it roams though. I think cingular might have more towers in more locations though. And they have those sim cards so you can put it in a new phone and not lose all your numbers and everything. I really like sprint though. I've had it for around 3 years.

I prefer cingular and I have a cingular phone. When a cellphone can work in a very small town you know that is a good cellphone service.
