Who else thinks protection for iPhone 4 is needed? 1. I added the bumpers from the Apple store on 15th along with iPhone but it shipped yesterday, so still waiting for it. And if I understand right, it protects only the sides of the device. 2. I am contemplating buying Bodyguardz pack which has a front and back protective film. This will prevent the phone from scratch and obviously not from a drop and shatter case. So, is the front of back protective screen really required?
