On the cusp of iPhone 4's official rollout tomorrow, Apple has issued a statement about why the white model, introduced alongside the black by Steve Jobs at WWDC 2010, hasn't yet been made available to order:
White models of Apple’s new iPhone 4 have proven more challenging to manufacture than expected, and as a result they will not be available until the second half of July. The availability of the more popular iPhone 4 black models is not affected.
So, anyone going to wait for white?
