I think the seriousness of that one was a bit exaggerated by the press, really. I mean, I used an iPhone 4 for 3.5 years. I could cause signal to drop a bar or two by pressing a specific point, hard. In general, I got better signal most places than with my old 3G. Maybe if you lived in an area with extremely poor mobile signal and held the phone a certain way it could be a big issue, but I never really saw it as a problem.
