Next-Generation iPhone to Offer Option of White Front Panel? [Updated]
While very similar to the traditional black panel seen in some previous parts leaks and in prototypes that have surfaced in recent weeks, it does carry an unknown physical feature directly above the earpiece slot. The feature appears similar to a "reflective surface" seen in another part leak back in February.
Apple has offered a white back on its iPhone 3G and 3GS models, with the exception of the 8 GB 3G model. If today's purported images do in fact turn out to be authentic, it appears that Apple is looking to bring that style option around to the front with a more prominent presence.
Update: The photos have since been revealed to have originally come from Chinese e-commerce site Taobao.com and were cropped before being posted at Apple.pro.
