I am picking up my new iPhone 3G today. But, I keep reading that people are experiencing very poor reception with 3G turned on. I hear that their signal goes from 4 or 5 bars to barely even 1 bar. Is anyone else experiencing this problem? If so, please include where you are from and how long you have had 3G service in your area. I'm just trying to get a feel for how widespread this problem is.
