Apple's flirtation with Corning and their superior Gorilla Glass was short-lived. I read something somewhere about Apple using (at the time of iPhone 5's, I think) Gorilla Glass v4, or 5. Anyway, the term they're using in marketing current devices is on the lines of "Soopa Doopa", "Secret Recipe", "Best Thing Since Sliced Bread" kinda stuff.
Back on the subject of Gorilla Glass I just came across an excellent article on DigitalTrends about the Corning Company and its' 166 year history: https://www.digitaltrends.com/features/cornings-glass-innovations-past-present-and-future/
