[Off-topic rant]What's the problem with AT&T? I had them back in the states for years and I never had problems with signal. A lot of times I would have five full bars when my friends with Verizon didn't have any. It wasn't like that in just one area either. I took several roadtrips to Florida and even in more remote parts of the country I still got service.
I can take you some place where nobody will get a signal without a satellite.I never had problems with AT&T either, it wasn't quite as good as Verizon in some places but I was very rarely without signal.
Of course, I can say the same for Sprint that I'm on now, in fact I have yet to be completely out of range.
