I had to get a new iphone4 today because the home button wasn't working properly. I had a few littel scratches on the screen of my old phone since I never used a screen protector. I find that the iphone 4 screen scratches much easier then my iphone 3g...
Since I had a brand new phone with no more scratches I decided to stop by the Zagg booth outside of the apple store and get the invisishield installed on the screen. I hope it works as good as they claim.
Check out the iphone 4 scratch test if you haven't seen it already:
