A white iPhone HD isn't exactly a new idea, but according to Apple.pro you're looking at the real thing lying alongside its black brethren. Going by the second photo - which you can see after the cut - the handset hasn't been fully assembled yet; there's a considerable gap around the home button, for a start. Still, the front-facing camera is far more noticeable on this lighter hued model.
If authentic - and stranger things have happened in the run-up to a new iPhone launch - then it suggests Apple have once again lost control of their supply chain. This is the most leaked iPhone to-date, and it's looking more and more likely that there'll be little in the way of hardware surprise come WWDC 2010 next month.
