If these photos are real, they are the best images of a fully assembled iPhone 6 we've seen thus forth. Apple plans to make the iPhone 6 thinner than previous iPhone models, along with rounded corners and other major changes to the design.
The images were posted by Feld & Volk, a firm which modifies iPhones and other devices with things like gold-plating and diamonds. Feld & Volk have been responsible for a few leaks in the past and the firm has stated that it has a few sources in Apple's supply chain, hence the leaked parts.
Apple is rumored to unveil the iPhone 6 at its September 9th event and expected to release the device a week or two after. Other changes to the iPhone 6 redesign are only having one row of speaker holes, elongated volume buttons, and a relocated power button, from the top to the side.
