Video shows purported next-gen iPhone 5 'uni-body' backplate in detail

ETrade Supply, wireless parts company, posted a video comparison of the next-generation iPhone 5 back cover and the iPhone 4S one. Noteworthy, the back shell of the forthcoming iPhone is identical to a part seen in previously leaked photos.

First of all, the side-by-side comparison shows that the iPhone 5 backplane will include aluminium chassis and feature "uni-body" design. The new component is so slim that it is noticeably thinner than the iPhone 4S. The physical button layout as well as the dual-antennas on the top and bottom of the device remain unchanged

The narrator notes that the SIM card tray is noticeably smaller than the piece found in existing iPhone 4S hardware. That suggests the tray could feasibly fit the new "nano-SIM" format. The video also demonstrates the much-rumored "mini dock" at the bottom of the unit which is situated next to revised speaker and microphone grills and a newly-positioned headphone jack.

This hands-on comes less than a week after a video was released claiming to feature the next-gen smartphone's front glass. It is unclear how thick the assembled shell would be if the two sections were put together, assuming that the two match at all, but Apple is rumored to be using in-cell display technology to keep displacement down. Disregarding the thickness of the panel, both leaked parts point to a display with a diagonal length in excess of 4-inches which is consistent with whispers saying the new iPhone will boast a bigger screen.
