I have a 16 GB Black 3G and I really really like it. I love all the apps and mail and safari and everything, with one exception....the phone Over half of my calls get dropped, and sometimes I can't even make calls - it just doesn't start ringing. I've had over half a dozen cell phones, all on ATT, and none have performed this poorly. I live in a 3G area with good coverage. Does anyone else have these issues? Anything I can do about it?
