With the MMS debacle ongoing, iPhone users are desperately looking for reasons to like AT&T. The company has started its 850MHz spectrum upgrade, which should improve signal strength in buildings and overall quality.
iPhone users in some urban areas are already reporting improved 3G reception and performance. AT&T has confirmed upgrades in Atlanta, Las Vegas, San Diego, Fresno and Stockton CA. Atlanta, for example, is in the process of getting 540 new 850 MHz cell sites next to the existing 1900 MHz towers.
