100% Happy with AT&T no dropped calls better service for me then my wife has on Verizon using her Droid. I have Visual VoiceMail without paying extra, I can talk and use the Internet at the same time, Huge for me since I am on conference calls a lot so I can browse around the net at the same time.
Great Phone, my only wish would allow us to customize the phone a little more with icons, better battery, and be able to change the default sounds for Calendar and Txt without a JB, other then that I am happy with AT&T and Apple.
