Then why should AT&T get to claim the fastest network if you can only access that speed in select places? That's misleading to people who live in the huge blank spots. Its all a bunch of horseshit on all sides.
Ok
1) You probably don't care about the blank spots.
2) Probably no one from this forum is from the blank spots
3) You probably wouldn't ever go there anyway.
4) On your road trips, you can get 3G coverage anyway. We listened to 3G radio on someone's iPhone on our 6 hour road trip.
5) 75% 3G coverage is pretty decent. I remember when cell coverage first came out in the 90s, we took a map ATT's size and said "Hey, I live in the cities. I'm not going to the middle of nowhere, I should be OK...." and it WAS ok.
I can bet like 99% of you who even post here ARE covered by AT&T's 3G network. The problems you face with AT&T are probably all capacity related and not 3G area coverage related.
