This is true. Unfortunately, nothing is quite the same as bare glass (obviously).

However, I've had my iPhone 4 covered (entire phone covered) by Ghost Armor since the first day I got it. Mainly to preserve it for selling later when I want to get a new one and not have to use a case. I'm very happy with Ghost Armor! It looks good and isn't as noticeable as some other covers. It was easy - the guys at the kiosk in the mall did the work for me and it was affordable. I think somewhere around $40-$45 for the entire coverage and it comes with some warranty too. I would recommend it to anyone.
