HTC EVO 4G :: Scratch Resistant But Got Long Crack On Screen

I was recently told by a Sprint phone "May I speak to a manager" guy that the EVO screen is Gorilla Glass, which he said, "Doesn't really scratch," even though I have a long crack on my EVO screen from just carrying it in my pocket with nothing else. (I've been so Honeymooning over it I haven't put it in my purse or backpack, or even in the same pocket as the headphones I use with it!)

My real question is:
Is there any way I can repair this? The touch screen works fine over the crack, and I can't feel it with the pad of my finger, but it is noticeable when I slight my nail over it. It runs from the start of the glass on the top to over a third of the way down the screen, and shows some pixel reflection, especially on white backgrounds. I'm willing to try at home methods, but do not wish to sand the glass down on the touch screen. If it can't be repaired, does anyone know of any screen protectors that minimize the visibility? I've seen some that bubble on the screen, and others that are so thick they make the scratch stand out.
