While we've seen dozens of part leaks for the 4.7-inch iPhone 6, parts for the rumored 5.5-inch version of the device have thus far been scarce, possibly due to the fact that the larger iPhone 6 is said to have entered production later than the 4.7-inch iPhone 6.

Photos depicting what might be the rear shell of the larger device have finally surfaced, however, and have been shared by Evasi0nJailbreak.com. According to the site, the photos have been sourced from "deep within Apple's supply chain in China," and may be only a prototype of the final rear shell.

That said, the 5.5-inch iPhone 6 rear shell images, which are compared in the photos to the rear shell of a 4.7-inch iPhone, do resemble early images of the 4.7-inch iPhone 6 rear shell, depicting thick antenna breaks, a rounded True Tone flash, a cutout for an embedded Apple logo, the camera, and the microphone.

More convincingly, the screw holes on the rear shell image accurately match up with the screw holes on an earlier leaked image of a logic board said to be for the 5.5-inch iPhone 6, so this may be our first look at a true 5.5-inch iPhone 6 rear shell.

Apple is expected to introduce the iPhone 6 at an event on September 9, but it is unclear whether the company will show off both the 4.7-inch and 5.5-inch models at the same time. If the 5.5-inch iPhone 6 does make an appearance at the event, it may not ship to customers until several months after the 4.7-inch iPhone 6 ships due to production delays.
