http://www.pcworld.com/businesscent...the_iphone_4_three_reasons_to_turn_it_in.html They pretty much hit the nail on the head, at least as far as I am concerned, especially reason #2 to turn it in. The proximity sensor. That is my main reason for turning mine in and since it looks like it will be more than 30 days after I bought mine before they get it fixed, I'm glad I did. Apple, fix that proximity sensor issue and I may just pay the ETF with Verizon to come back to you. Anybody else think the proximity sensor issue is bigger than antennagate?
