This isn't the first time we've seen a supposed Lightning port and headphone jack assembly. The part was also posted by MacX last week.
Notably, the screw holes appear to line up with a rear shell that has also been leaked by apple.com.tw. While having a cutout, the Apple logo doesn't appear to light up on this shell, reports the site. In addition the antenna breaks on the back are prominent, as previous leaks have shown.
Take a look at the leaked parts below and please follow iClarified on Twitter, Facebook, Google+, or RSS for updates on the iPhone 6.
