I think the interesting bit is that Apple apparently isn't capable of producing a white iPhone. They've missed their deadline by 4 months already and they've just announced another 4-5 month delay.

Technically no one knows exactly why the white iphone hasn't been released. I've seen plenty of solid 'leaks' claiming button colors and camera problems, but no one really knows the real reason. It could be strategic for all anyone knows at this point.
