I had read that the iphone 4 is supposed to have better reception than the previous iphones. However, in my apartment my iphone 4 is regularly at 0 bars and often goes to searching. Sometimes it spikes to 3 bars, but usually when I look at it there are 0 bars. My iphone 3g would always have like 2 bars most of the time. Does anyone else have reception issues? This has nothing to do with holding the phone a certain way.
