Black and white next-gen iPhone leak: Smaller dock, metal rear, larger display, headphone jack moved
You're looking at what's believed to be the rear panel of the next iPhone (above.) The part was uncovered by iFixYouri, which was tipped off by a "reliable source" at a Chinese parts supplier (the same source who revealed that the iPad 2 would be available in white) who already has the parts for sale. 9to5Mac was able to get even more images of the device.
As you can see in the image, the rear casing matches up quite nicely with recent rumors. We see the rear metal backing (although this is aluminum alloy and not LiquidMetal,) a spot for a much smaller dock connector, and larger speaker grilles as well. In addition, the sides of the device are incorporated into the back piece, and it appears that the headphone jack has been moved to the bottom as well, similar to the iPod touch.
Of course this is all rumor and speculation at this point, and even if real, plans can change at any time. Continue reading for more images!
