I live in Adelaide, South Australia, a city of 1 million people, in Australia, obviously. I have had the iPhone for a month, and I have had no problems, whatsoever with 3G coverage. So the problems reported here are not iPhone problems but carrier problems (AT&T?) I am using Optus, and have always been able to have 3G coverage. If Adelaide can do it then seriously, EVERY place in the US should be fine, unless AT&T are screwing up.
