All of a sudden this morning I get "No Service" signal at my work when I usually get full signal at 3G speed for my 3G Iphone. 5 other people from my work also now get the problem when before we all get the full signal. My wife who works for other company and somewhere else also got the same problem with her 3G Iphone? Is AT&T service down? Anybody else has the same problem? I'm in Southern California
