In late May, we had exclusive high-resolution photos of both black and white next-generation iPhone backs. These backs showed a brand-new, thinner design with a smaller dock connector, new speaker grills, and a new metal back plate. Now, ETradeSupply – a parts reseller – has gotten their hands on these already leaked parts (via CydiaBlog). They have posted a video to YouTube (shown above), and the video does not show anything different than the photos, but it is nice to see more of a hands-on demonstration of the unreleased iPhone parts.

Other findings from our photos that are affirmed by this video include the unibody/integrated approach for the antenna band and back portions of the device, a relocated headphone jack (now on the bottom), and an overall taller design.

The videographer of the parts believes that the SIM card used in the next-generation iPhone will be smaller than the MicroSIM card used in the iPhone 4S and iPhone 4. However, this is based on the SIM card holder piece itself being smaller in the new iPhone back piece, rather than a measurement of the actual SIM cutout in the part itself. While a smaller SIM card standard is being developed, it is hard to tell whether or not these smaller cards will make their way into the new iPhone.

Some nice big stills (click to enlarge):

We are expecting to see this new iPhone launch sometime in the late summer/fall. Thanks Norin!
