My gf brought her iPhone into the Apple Store to have them look at what we thought was a few dead pixels. Anyway the Genius told us it was just dust and that they would replace the phone. Then he stopped and said, no wait we have a new procedure for this issue which is to replace the glass on the premises. So he went in the back, came back 5 min later and it was all set. In general a swap would be nice, but this was actually pretty cool. I think anyone who has dust, scratch or even a nasty crack might get a break at an apple store since they can do it there instead of swapping or sending it out. Just wanted to pass on the info.
