I think we need to start a mass movement to protest against AT&T.. I live in the Los Angeles area and everyone that I know of has problems with the coverage.
I wish they stop counting the money and start addressing the problem.
I called them and all they could say was that they were sending technicians to look at the towers and expected it to be restored in a week, but nothing of that sort ever happened. The only improvement has been that my home went from being in the dead zone to a wave zone (the conversation fades in and out like a wave) and that is more irritating than not having coverage.
