I had my day 1 iPhone until last week. The wifi conked out and I took it in for replacement. I was not happy with the replacement unit. The lock button was spungy not clicky and the silence switch was loose. On top of all that the screen was a lot more yellow then my original screen. I take it in to replace that phone and the new phone is all good except the LCD. The LCD is tinted yellow again. White doesn't even look white, especially from certain angles. Compared to another 3G, my phone is a lot more yellow. My question is, is there anyone else experiencing this? I did a search and I guess this was a problem with the initial run, but is anyone else having to switch out their phone multiple times until they get a phone that isn't all yellowed out?
