What good experiences do any of you have with particular carriers and the use of Blackberry devices in the North Central Illinois area. (DeKalb, Genoa, Belvidere). I currently have Cingular for my cell carrier and they are really frustrating the heck out of me with horrible service. Don't get me wrong it is not all their fault, it is partially mine since I live in a farm field. I just don't want to get a blackberry and not be able to use it in my home area.
