Whether the proximity sensor issue happens to me or not depends almost entirely based on who I'm talking to and what I'm talking about!! When I'm talking to the person I'm going out with, I tend to move my head more or something so it happens literally EVERY SINGLE CALL. When I'm talking to close friends, it also happens often especially if we're having an animated conversation. But when I'm talking to coworkers or my parents, it never ever happens! This is why some people report the issue, and some don't because some people keep their heads perfectly still while on the phone while others move it more. Regardless, the proximity sensor issues annoy the crap out of me. I have to drive 3 hours to get to the nearest apple store, and I would lose my jailbreak. So I don't want to drive to exchange the phone unless I know that the problem is fixed in the new phone batches. Can anyone confirm that the hardware is fixed? I've seen many reports of people exchanging the phone only to have the problems persist. Also, didn't apple promise a software fix for the issue asap, like two months ago!! Where the hell is the software fix apple? Does one even exist? Or was the promise of a software fix just a lie/delay tactic? My bro's 3GS never had these issues, even on iOS 4 so I can't help but wonder if the problem actually exists in the hardware and if it will ever be fixed.
