I know that iOS4 Black Screen after Calls often happens.

Me thinks op was a troll due to the fact they only posted once. Anyhoo, so I've read the replies and it seems to me that you guys/gals believe there was a unannounced hardware change to fix the proximity sensor issue. If I get my i4 next weekend, and I have the proximity sensor issue will they just exchange it?
