Are you AT&T users in Cincinnati getting good coverage for voice and data, including 3G?
I'm currently with Cincinnati Bell wireless, but since the iPhone 3G is now only $99, I'm considering switching. I haven't had any problems with CBW, but I also don't have a smart phone, still using my old crappy Razr. My big gripe I have with Cincinnati Bell is thier phone selection flat out sucks, and they charge you a fortune for the higher end devices.
I haven't heard to mean good things about AT&T in this area, lots of people complaining about dropped calls, poor voice quality, and many dead spots.
