UkranianiPhone.com has posted images of what it claims are iPhone 6 renders aimed at helping manufacturers produce accessories for the upcoming device.
The images appear to be better quality versions of the schematics leaked a few weeks ago. They depict the full-metal backplate with inlets at the top and bottom, assumedly related to the antenna structure. The cutouts for these lines match the image from the previous leaks. Interestingly, the renders also give specific measurements saying that the phone is 138mm in height, 67 mm in width, and 6 mm in depth.
This is slightly taller and wider than the current iPhone 5s, which measures 124 mm by 59 mm. These sizes point to a screen of about 4.7 inches, as suggested many times before. These dimensions mean the iPhone will be similar in size to the Galaxy S5, albeit a tad shorter, for comparison.
Although not entirely clear, the renders seem to suggest that the Home Button may be getting slightly smaller. Unlike the current iPhone, the side edges are more rounded similar to the industrial design of an iPad.
The site posted images of the iPad mini in early October 2012, so has a reasonable track record of accuracy. The fact that these shots line up with the previously leaked schematics (shown below) also helps improve their reliability.
