I never said anything about that. I said yellow screens suck. Because they do. Find one iPhone at the Apple with a yellow screen. Look at my above link on page 2. That yellow screen worked the same as the blue one but who would ever keep that? Your 1 out of the 100 who are contempt with yellow. I also know if you had the option to get a white screen, you would in a second

You wont persuade anybody that the left screen is normal.
Actually I wouldn't. I don't mind it. Mine isn't as yellow as the picture you provided, but it's still yellowish. It doesn't bother me at all. I compared the screens with my iPod Touch (It's blue) And I actually prefer the yellow one.
I have more things to worry about than the colour of my iPhone screen. You'll understand when you get older.
