How I fixed my proximity problem

First the history. I have tried 3 iPhone4's with no luck on the proximity issue. My wife has no problems with hers but I do. By accident I was talking on phone and had my ear on the center of the screen. Since using the phone this way, have not had an issue with dialing, muting , etc.

I believe many of us, by default, place that little hole on the phone over our ear canal. It just doesnt work for me. Put the center of the screen over your ear when talking. You can hear fine and will stop the annoying dialing etc.
Hope this helps.
