So I got three iPad 3's (can't get used to the name The New iPad) today. 1 in black and 2 in white and glad I did so I can compare them. Sure enough one of the white ones has a warm yellowish tint and the other two have the crisp blue tint. I was really against the yellow tint on my 4s that's why I returned it cause was so used to the blue temp on my 4. After looking at all the screens side by side I can see how some people would like the warmer yellow cause it would be good for photographs and skin tones. To me it looks a little muted and the blue is more crisp/alive and whites look whiter and well blue and eye catching. So if your's is warm/yellow then there are ones out there and you might get lucky if you're unhappy and exchange it. Might post pics later but too busy messing around with them now
