There have been a number of photos, both alleged to be actual photos and physical mockups, that have leaked in recent weeks, but a set of photos at Chinese site NetEase show in decent detail both the interior and exterior of the shell. The part is said to be a legitimate rear shell leaked form a manufacturer in Shenzhen, China.
The pictures show a number of details of the rear shell, including the opening for Apple’s smaller dock connector expected to debut on the iPhone 5 next week, a rear camera hole, and the interior lip where the display and front panel will be attached. The shell appears to be for a Wi-Fi model, as it lacks a cutout for a SIM card and an open section along the top edge for a plastic window covering where the cellular antennas would be.
