Actually, I don't think the iPhone 4 and iPad have Gorilla Glass. Here's one independent source stating as much, and I don't think Apple has ever directly claimed they use Gorilla Glass.

The iPhone4 is Corning Gorilla Glass... both the screen and the back glass. Apple and Corning have both stated that it is. . . Steve Jobs stated it as a fact in the introduction of the iPhone4. The glass is made by several manufacturers under license from Corning.

As for your link to the scratched iPhone: Again, you find the stuff from the fringes and post it as fact. I have many friend with iPhone4s and none of them, including myself, have succeeded in scratching our phones.

Great, I’m sure you can provide a reference? I haven’t been able to find anything other than Apple saying it’s an aluminosilicate screen...
