A set of images depicting what is said to be the shell of the next-generation were shared with MacRumors by an anonymous Twitter user earlier today. Australian writer Sonny Dickson, who shared several of the same images, claims that they were initially shared by someone in China.
It is entirely unclear whether the device in the images is a legitimate iPhone 6 part or a fake. Early prototypes of the iPhone 5s and the iPhone 5c exhibited a blank rear shell while the iPhone 6 shell in the picture clearly shows FCC text that is generally added to the phone at a later date.
The device depicted in the images has a width of 2.6 inches, while the existing 4-inch iPhone 5s has a width of 2.31 inches.
Even if these images are fake, they give a good idea of what a larger screened iPhone 6 could look like.
