Well I'm at Bristol Moter Speedway. It's an awsome track and beautiful country out here. There is no 3G coverage, just edge. No big deal. Get this. My iPhone doesn't work worth a crap from the track or inside of aile radius if the track. I show full bars and it goes back and forth from 3G and edge, but I can't make calls or anything. Only texts work sometimes. Get a few miles from the track and all is good. Do you think Sprint is jacking or blocking other carriers signals? Or is that possible?
