If the images are legit then it confirms what we already know about the upcoming iPhone 6. Apple will reportedly release it in two new sizes; 5.5" and 4.7", which are shown in the above pictures.
The rear will now feature a curved aluminium back rather than a squared one like the iPhone 5s. The images also show the sleep/wake button has been moved to the right-hand side of the device, which is in-line with recent rumours.
It's highly likely that the iPhone in the pictures is just a plastic dummy model and not nearly close to the finished article. It does not have the customary Apple logo on the rear and the camera hole and ambient light sensor on the front of the device look much too small to be the real thing.
Expect many more images and details to surface as we near the iPhone 6's widely rumoured September release date.
