A new set of images has today been posted showing what appears to be an iPhone 5S in black and graphite color. The image comes from Sonny Dickson who has spent the past few weeks posting various images of what is purported to be a champagne/gold colored iPhone 5S, with the black/graphite option now added alongside a black/slate and white/silver iPhone.
The source of the images is not clear and, in fact, the device displayed looks not unlike the current black color iPhone when viewed in a well-lit room. The only differentiating factor seems to be the chamfered trim which shows the new graphite color well, when compared to a black iPhone.
The interesting question seems to be whether Apple will still go ahead and release white and black versions of the new iPhone or whether the gold and graphite options will be the predominant differentiating factor for the new iPhone 5S.
