Apple iPhone 5 blueprints appear live on Developer website
Detailed blueprints of Apple's iPhone 5 that have been created for use by aftermarket product manufacturers have appeared on Apple's Developer website. Unusually, despite being posted on the Apple developer portal, the link to the document (pdf) appears to be accessible by anybody. @JoelJohnson made the find and posted the link to his Twitter account.
The blueprints advise case makers not to make metal on metal contact with parts of the iPhone 5 that are made from aluminum. It also advises case makers not to obstruct the rear glass portions of the device with metal as these were deliberately designed by Apple in this way to reduce the radio interference that would come if they had used an all-aluminum back case.
More obvious directions include advising case makers to avoid covering acoustic openings including those for the front mic, rear mic, earpiece and speaker. The same advice applies for cameras, the flash, and sensors. Also provided are detailed measurements of the iPhone 5. It is yet another detailed insight into the iPhone 5, ahead of the device actually going on sale, joining the numerous accurate leaks ahead of its formal launch last Wednesday.
