I have an iPhone 3GS, with a problem. It has a nice scratch in the middle of the screen. It's not a deep scratch, although I can feel it when I run my nail over it, and is definitely noticeable. I did a little research and bought some Applesauce. Then through a combination of laziness and fear, I decided not to actually use it, and just wait for the iPhone 4G to surface. Having seen the leaked iPhone 4G images, I admit I'm not totally bowled over by the way it looks (a debate for another day!), so I'm now more inclined to try and remove this scratch! Has anyone used Applesauce on an iPhone 3GS before? Any reasons not to use it, or risks attached? Given that I'm essentially rubbing liquid-sandpaper into an otherwise unblemished screen?! Cheers.
