Many iPhone owners will tell you that the biggest problem with the device is the AT&T network. The network has a frequent habit of dropping calls and lacking 3G coverage in all but the largest cities. The poor network quality has led many iPhone users to complain about missing features like MMS and the inability to stream video over 3G.

AT&T is reportedly trying to remedy the issues on its network by rolling out upgrades to its 850MHz spectrum earlier in some areas. The faster roll out will mean better 3G coverage in major cities, but will leave those of us in more rural areas with the same shoddy network.

The first city to get 850MHz is Atlanta, which was upgraded this week. Customers in the city will be served by 850 more cellular towers that will operate with the existing 1900MHz towers. CNET also reports that upgrades are underway in the San Francisco area as well.
