I just check the map and theh 3G network comes up to about 1 mile from my house...
I has Cingular when it was BellSouth and even after the change for a while. I was very disappointed. I was always loosing calls in areas where other providers didn't.
I had been with Cellular One (now Verizon in our area), no problems.
PowerTel (now T-Mobile) for a couple of years, no problems.
Switched to BellSouth (now Cingulare) because of my company provided the service for 2 years.
Now I'm back with Verizon and don't have any majors complaints about the coverage... (ok, maybe ONE BIG ONE...there is one spot that will always drop the call and it seems I am always talking to my wife when I drive through this area. Even if I tell her it's about to drop she gets mad...) (sorry, needed to vent.)
Will I switch? I doubt it. Even though Cingular has updated their network in our area, I still have lots of people complain about it. (I deal with a bunch of doctors and their Tech Toys... PDAs, SmartPhones, computers, cameras...)
At the current price points, not even if I save up until Christmas.
Unless the company ponies up for it, I'll just sit back and wait for one of the Docs to get one and bring it to me to show them how to use it.
