The mysterious and semi-mythical white iPhone 4 just can't catch a break. First Apple acknowledges the phone won't see stores before this Spring; now Cult of Mac is reporting that the reason may not be a manufacturing issue at all. Instead, the phone's white case and the rear-facing camera may be interacting in a downright uncooperative way.
The CoM source suggests that the white iPhone case leaks light into the camera sensor, resulting in washed-out photos regardless of the subject lighting. The problem was supposedly identified very late in the game at Apple's testing center that qualifies cases for use with the phone.
