If your iPhone 4 definitely needs to be replaced and you're sure that you will receive a replacement, I think eveybody here would like to see a scratch test of the front, back, and steel of the iPhone 4. Just a key-to-iPhone test on video. You can stop as soon as any significant scratches start showing up just to demonstrate what it takes to scratch the front, back, and steel on the iPhone 4. It would be appreciated if anybody is willing to do it.
