Gorilla Glass, Apple chipsets proudly made in the U.S.A.

As part of his D10 Conference interview last night, Apple CEO Tim Cook used the occasion to once again respond to critics of Apple's China policies and remind them key parts of the iPhone, iPod touch, and iPad are in fact made in the U.S.A -- including the Corning Gorilla Glass screens and the Apple A4, Apple A5, and Apple A5X chipset "brains".

The story of how Apple came to use Corning's Kentucky made Gorilla Glass for the iPhone is well known, involving Steve Jobs, some keys, a scratched iPhone prototype, and a demand to change an entire manufacturing process just weeks before launch. Apple has previously admitted and even touted the connection on their jobs creation page.

Samsung, who fabricates the chips designed by Apple for the iPhone, iPod touch, iPad, and Apple TV, shifted manufacturing to Austin, Texas some time in 2011. The Apple A5 chipset found in the iPad 2 and iPhone 4S, and likely subsequent chipsets have been produced there ever since.

Riffing on Apple's ongoing patent litigation, which was also discussed, Cook went on to describe how Apple is taking the lead in supply chain responsibility, making it more open and transparent, and reporting on progress more frequently than ever before.

Rather than stealing Apple intellectual property, Tim Cook said he wished Apple competitors who rip off some of that.
