iPhone 3G yellow screens explained

Though Apple claimed that the iPhone 3G’s screen was the same as the original’s, users are discovering that their devices’ screens exhibit a noticeable yellow tint when compared to the screens of the original iPhones. iLounge’s extended Live iPhone 3G Comparison Test, however, shows a subtle difference by comparison with the blue-tinted original iPhone and the differently colored iPod touch, noting that each screen possesses a slightly different white balance, with the gray-white iPod touch having the most neutral coloration. Additional user reports suggest that the yellow tint may be bothering some users, and it is currently unknown how much tint is in different units’ screens, or whether Apple will replace especially affected units.
