HTC does not use true gorilla glass. Motorola does, however, and I believe Samsung does as well. I've tossed my OG Droid out of the car window going 75 and it hit the rumble strip. The top frame around the glass was impacted pretty hard, and you saw the shiny metal gouges. The glass was completely intact, even at the impact edge. I wish the whole thing was made of it, it is crazy tough.
The answer is 42.
Oh, wait, you mean to tell me you need to know the question now?
Well, I can't answer that.
