Besides the gray/graphite model recently posted by the blogger, there is also the gold iPhone that appears in new leaked images.
The images are claimed to be from Apple’s Asian supply chain and they show a rear housing for the gold version of the iPhone 5S.
The model features white bars at the top and bottom ends.
In addition to an iPhone 5S in black, white and gold, a gray model of the smartphone is said to be in preparation.
