Hi, I've been using iPhone4 for about 2 months and I noticed that the "Home" button is starting to get pretty scratched up. This is obviously my fault because I have long nails and frequently accidentally used the nail to press the button. My question is: What can I do to fix the scratches, or at least make them less visible? I was only able to find posts about fixing scratches on the BACK of iPhone 3g,3gs. I fear that they might be made out of different plastics and it might make things worse (cause the home button is clear). BTW, anyone had experience of using guitar polishers cause it looks very similar to "iDrop" thing?
