[Imprecate]

There are areas where I get great data service when nobody else is around. Then during peak hours data service is very slow or intermittent even though my signal strength stays the same. I'm not a telecom engineer, but it seems like they have too few towers for the number of subscribers in some areas or they don't have enough bandwidth in their backhaul.

Maybe both AT&T and the iPhone are bad, at least in my case.

When I travel to less populated cities, 3G data is always extremely fast; still I'd rather have a consistent 800 Kbps than 1500 when I'm lucky and 50 when I'm not.
