Listen. I've been yelled at because of this before but here it is again. I like AT&T. It has very good coverage around here. The nokia I have works great, and the customer service has been more than I could want. I have used sprint, and yes the calls are clear, and cdma means no "hard handoffs". However I never had a good signal, and it was useless indoors. and no I don't work for AT&T. It's up to you as it is a very personal thing, but I like mine. (also as a footnote, I was nabbing some caches in the mills, and had four bars of stregnth down in a valley, a big valley. If I had gotten hurt I could still have a line to help. That makes me feel good about caching in remote places)
