I had 4.2 GM on my iPhone but the proximity sensor is still not working properly, so I downgraded my iPhone back to 4.1. But obviously the modem firmware never got downgraded.... If I take my iPhone 4 into the apple store to get them to exchange it, are they going to turn me away cause I upgraded the phone to 4.2?
Currently its running:
4.1 (8B117)
Modem Firmware 03.10.01....
