Currently using a blackberry (Verizon), but I really want to get the new iPhone. I live about 35 minutes outside NYC so I do have 3G coverage in my area. My Concern is call quality and calls being dropped. In the Mossberg reviews he complains about calls being dropped on the West Side Highway in Manhattan. How bad is the AT&T service and how does it compare to Verizon? Has anyone switched from Verizon to AT&T? If so, How is it?
