Most notably, the chassis does not have antenna bands running across the back of the device. There are still antenna bands running along the top and bottom. This corroborates previous reports we've been hearing.
Additionally, the camera cutout is noticeably larger than on the current generation on iPhone. It's also closer to the side of the device.
Another recent iPhone 7 leak allegedly showed a case for the device that did not have a headphone jack and had what appeared to be cutouts for stereo speakers.
Apple isn't expected to unveil the iPhone 7 until this fall. Please follow iClarified on Twitter, Facebook, Google+, or RSS for updates.
