All these years, Apple has kept quiet as to whether it has been using Corning's tough Gorilla Glass in its products. Today, Apple finally confirmed that it is indeed using Gorilla Glass in most of its shiny gadgets. In a recent job posting Apple has listed the following:

This figure also includes workers in Texas who manufacture processors for iOS products, Corning employees in Kentucky and New York who create the majority of the glass for iPhone, and FedEx and UPS employees.

By the sound of it, it looks like Apple isn't able to be protecting all of its iPhones with Gorilla Glass most likely due to the high demand and rapid production. Gorilla Glass 2 debuted at CES 2012, a thinner more resilient glass that will be used in mobile touchscreen devices. Until someone comes up with a solid way of finding out which iPhone is fitted with tougher glass screens, you'll just have to find out the painful way. Let's hope Apple uses Gorilla Glass 2 in the iPad 3.
