[citation][nom]Travis Beane[/nom]I believe the front glass of the iPhone 4 is made out of this stuff.This stuff certainly isn't new. What makes it interesting (to me) is that it's flexible. You try to bend normal glass, it shatters right away. You bend this stuff, it takes a while before it shatters. Not immune to scratching, but it's still pretty tough.[/citation]
Regular glass is very flexible too. The problem is, that when it is scratched, it loses it's flexibility very rapidly.
