I'm sure some areas are much better for AT&T coverage. I just saw an article about AT&T's 3G service expanding significantly in NY.
But here, in the SE, AT&T doesn't have the same penetration, tho they (supposedly) are expanding the number of towers here in my town... which they should do, if for no other reason then one of AT&T's Board members is one of this community's leading citizens. I know it must be embarrassing as heck for him.
