I'm getting my first iPhone and would like advice on protecting the front screen. I have an iPod Touch 2nd gen and even with babying the thing it has a scratch. It is just a tiny one but it is noticeable because the light shines through that spot differently. I really have babied it, keeping it in a case, not putting it in my pocket with other things, etc. I would be extremely upset if the same thing were to happen to my iPhone. Have the materials improved enough with the iPhone 4 not to have to worry about scratches? If I need to buy a protective film, which one? I really love the smooth feel of the glass on my Touch, is there a protective film that preserves that feel?
