Geographically speaking, AT&T lacks 3G across hundreds of thousands of square miles of its coverage area.

Even after six years of deployment, total AT&T W-CDMA overlay still extends to only ~50% of its native footprint. And much of that 3G is padded out with the RCC and ALLTEL coverage in the central and western states that VZW divested to AT&T and that AT&T converted to W-CDMA just earlier this year.

By comparison, VZW and Sprint each have had nearly 100% EV-DO overlay already for several years.

As I said then and maintain now, Cingular made a mistake -- at least from a coverage standpoint -- almost 10 years ago when it decided to transition from TDMA to GSM.

GSM forced Cingular to follow the W-CDMA migration path. And W-CDMA has always been a Eurocentric airlink. It was designed to be deployed in 10 MHz blocks of new, dedicated 3G spectrum. That was the reality in Europe but not in the US. W-CDMA, spectrum wise, has oft been an awkward fit here, and deployment has lagged behind because of that (combined with AT&T's duopolistic sloth).

Cingular would have been better served to transition from TDMA to CDMA. Then, AT&T could have transitioned from CDMA to LTE, just as VZW and Sprint are in the process of doing now.
