Few new details can be determined from the photo, but the relocated power button on the side of the device can be seen, and it is clearly a high-quality mockup given differing materials and colors used for various features such as the rear camera and flash. The size of the device is not given, but just based on the look in the hand it appears to be the 4.7-inch iPhone 6 rather than the even larger 5.5-5.7 inch version depicted in the less refined physical mockup from earlier today.
The latest mockup is reportedly the work of a case manufacturer, and Macitynet understands that mockups have been refined over a period of months. According to the source, the version shown in the photo is considered to be "final" for the purposes of ensuring case and accessory compatibility with the expected design of the iPhone 6.
In practice, this model would be made molds of the latest cases and tested the prototypes of the enclosures to verify their compatibility with the real iPhone 6. It is not uncommon that during the process of engineering accessories manufacturers are forced to progressively refine their plans, as they come, of course, under the table, information on the specifications of the phones. In practical terms, it was explained, in recent months there have been various "versions" experienced by manufacturers of accessories (and these were modeled and rendered drawings of the iPhone 6), but there is now confidence that this one located final.The 4.7-inch iPhone 6 is reportedly scheduled to launch around the usual September timeframe, while the larger 5.5-inch is rumored to be arriving several months later.
