The white iPhone 4 has been something that was initially promised but has never materialized. Manufacturing problems were blamed, but specifics were not given out by the reticent Apple.
As luck would have it, apparently a man was spotted at a New York press event with one, and he said that a friend hooked him up and that Apple had plenty of them now. He commented, Apple is having trouble getting its two suppliers in the Far East to match the white used in the manufacturing of the parts.”
Whatever the reason, the white iPhone 4 is still not listed as available for pickup.
