Want to know why I’m still with Verizon? It’s mainly because AT&T’s voice network is lousy. But below I’ve grabbed their data coverage maps for the area I spend the most time in.

Verizon’s Data Coverage – 3G is in dark green

AT&T’s data Coverage. 3G is in dark blue.
Note: no 3G where I live, nor where my parents live. In between, there’s virtually no data coverage at all, save for some narrow strips of EDGE.
If you go to AT&T’s coverage map, you might notice that you can’t even view quality of service or 3G coverage. I guess they’ve seen those Verizon “There’s a map for that” commercials. By the way, these tiny dark orange splotches on the coverage map are places where you can expect your iPhone to work for phone calls indoors.
