I just got my iPhone today and immediately I noticed a difference in the screen compared to my Dad's iPhone 4. There's a very noticeable yellow tint on the entire screen, not just a blotch or a spot. Will this yellow tint go away after a few days of use? I heard that the bonding agent wasn't given enough time to dry. I don't want to bother my Dad with another trip to the Apple Store. What do you think?
