Hello, I had Apple install the Belkin IvisiGlass Ultra installed with the machine at the store. This was supposed to be the best protector they told me. Today as I was out for my walk, I sat for a minute and when I got up the phone fell out of my vest onto the ground about a one foot drop. Now I have two cracks and I cant tell if the larger of the two went through to the screen. Am I wrong to think this screen protector should nto have cracked so easily? Thanks.
