I'm sure this has come up in the forums before, but I thought I'd share something that worked for me and my scratched antenna. My wife put my iPhone 4 on our iHome dock the other day and scratched the hell out of the bottom of it trying to get it on. (Because my port cover was in and she didn't realize it.) The scratches have been bugging the crap out of me and I finally decided to do something about it.
DISCLAIMER: If you do this and make your phone look like crap, do not blame me. Your antenna will not look exactly the same as when you got it after you do this.
If you take one of those green scouring pads (like the ones you do dishes with) and gently rub it along the spots where you have scuffs or scratches, it will kind of re-brush the finish on the antenna. It will make some streaks on the antenna, kind of like what you see on your silverware, but if you do it gently and uniformly, it will look better than your scratched up antenna. I finally tried this today and am pretty happy with the result, however, I didn't do this on the whole antenna, so if you compare some different spots on the antenna, they don't look exactly the same in direct light. In normal indirect light, you will not really notice the difference.
Anyway, just thought it may come in handy for some of you. I have had way more problems with the antenna scuffing than the glass scratching and this worked for me pretty well.
