It depends on the geography. If you're in the city full of skyscrapers and tall office buildings, you might experience some sketchy 3G coverage. At work, when I stand in the middle our floor, I get next to zero reception or data coverage. When I walk about 5 feet away from the exact center of our floor, I get 2.5/3 bars. Try toggling the data toggles around and see if that fixes it. A few months ago I had zero 3G for a few weeks out of the blue at home, then it came back.
