I had two different iPhones over two years. I experienced dropped calls all the time. It was awful. I hated AT&T. During this time, I even moved from the East Coast to the West Coast and still had the same poor experience. I was ready to leave AT&T. I had friends on AT&T that didn't have iPhones and they said they had a good experience with AT&T. So, I decided to get a new phone. I got a Samsung Focus running Windows Phone 7. Now, my experience is really good. The network seems fast and reliable. No more dropped call issues. I can't speak for everybody. But, this is my experience. I wish I had changed phones sooner. It would've saved me tons of aggravation.
