Sorry folks.... looks like HTC isn't in contract with Corning for their Gorilla Glass product. Doesn't that royally suck, huh?
Gotta buy Samsung or LG in order to have bullet proof glass on your PDA.
CORNING® GORILLA® GLASS
Oh well, at least I saved everyone time from asking the SAME question.
From the Corning website you linked:
"Due to customer agreements, we cannot identify all devices that feature Gorilla Glass."
However, they have a list of some devices which do have Gorilla Glass and include the following for HTC.
"HTC: 7 Mozart, 7 Surround T8788, ChaCha, Aria, Desire, Desire HD, Desire S, Desire Z, Dopod A6388, Dopod T8388, Dragon, Droid ERIS, Droid Incredible, EVO 4G, EVO Shift 4G, G1, G2, HD2, HD7, HD mini, Hero, Incredible S,
Inspire 4G, Legend, myTouch 3G, myTouch 3G Slide, myTouch 4G, T9199, Thunder Bolt, Tianxi T9188, Salsa, Trophy, Wildfire, Wildfire S"
I'm guessing they have just recently updated their list since you didn't see it there earlier.
So, despite some of the people who have scratched their screens already, Corning is claiming the Inspire 4G does have Gorilla Glass.
