AT&T "doubling" 3G network for iPhone 3G
AT&T today announced that it has started "doubling the capacity" of its 3G markets, stating that nearly half of all cell sites will receive additional 3G capacity by the end of the year.
The company claims that its 3G mobile broadband network is currently available in nearly 300 major U.S. metropolitan areas, with "plans to expand to nearly 350 by the end of the year."
The map below shows AT&T's current 3G network (in blue). While coverage does indeed cover most major metropolitan areas, large swaths of the country and many states are completely excluded from coverage where EDGE access is plentiful. In the image below, blue represents 3G coverage, while bright orange represents EDGE coverage, and lighter orange represents partner coverage.

I don't believe there is a difference. This is indeed the 3G coverage map, and most of the US is NOT covered. The data coverage map you're looking at includes EDGE network coverage which does cover most of the country, but is significantly slower.
When you zoom in on the AT&T Data Coverage map the 3G coverage can be seen.
The 3G coverge is very metro. Most areas do not have 3G coverage and most metro areas are not linked up to another metro area for continuous metro to metro 3G market coverage.

- On the data map the 3G coverage is the dark blue area, which is the same as 3G area on the voice map. The lighter blue is EDGE which is not 3G...
