IPhone 4 scratch repair? Any ideas?

Hmm.... Interesting. Well, I would contact Apple first, and ask them about the phone repair/replacement. If they say "no", then I think I may have an idea. When my Nintendo DS Lite's LCD screen got all scratched up (Top and touch, somehow), I had some of this disc repair stuff from GameStop. It costs around $7.99 for a bottle of the stuff, and I have to say, I'm impressed. It works awesomely on my video games, CD's, DVD's, and my Nintendo DS screens. As long as the scratch on your screen isn't to big, it should work. Just be careful, 'cause this is just my theory. This may or may not work on your screen, and I'm claiming no responsibility if you damage your phone. Follow the instructions on the bottle.
