The site says the schematic is intended to calibrate the machines that affix the Apple logo and iPhone product name to the back of the device.
According to the diagram, the width of the next generation iPhone will be 85mm (3.35 inches) and the height will be 150mm (5.91 inches). A screen width of approximately 2.7 inches and height of 4.79 inches would result in a diagonal of 5.5 inches.
Earlier today we posted on another two schematics that were published in MacFan. Unfortunately, we have yet to obtain those in a high resolution; however, you can check them out here.
