My iPhone 4 speculation seems to have been correct; the white iPhone 4 is proving troublesome when it comes to its color. Engadget reported on it earlier this weekend:
Specifically, the factory's still working out the perfect combination of paint thickness and opacity -- the former to ensure the next sub-contractor has enough clearance for the digitizer overlay, and the latter for the absolute whiteness that Jony Ive and co. strive for. As we pointed out before, the prototype white covers we acquired appeared a touch darker than the iPhone 4 dock, so here's hoping that we'll see a better result when the official white phone comes out later this month.
We wish Apple would have had this figured out before launch, but at least those holding out for the white iPhone will rest easy knowing it'll be available in limited quantities by the end of the month. And just imagine: it'll be the perfect shade of white.
