EDIT (3/05/2012): Well based on this post it turns out I'm wrong --------------------- This appears to be a common misconception. iPhone iterations prior to the iPhone 4 used Corning Gorilla Glass, as evidenced on page 471 of the Steve Jobs biography. With the iPhone 4, Apple began using Lens Technology International to manufacture their aluminosilicate glass. This was the supplier responsible for the white iPhone 4 delay. Furthermore, Corning's Gorilla Glass website does not list the iPhone as a product.
