I have a case and a double (front and back) screen protector on my iPhone 4. So far, the phone is perfect. I was wondering if I can take off the screen protector off the front, because it is just annoying. There are no scratches on the surface of the protector, and the phone mostly sits in my hand or in my pocket with some lint. Can someone with experience with the iPhone 4 please tell me if the screen is capable of withstanding normal, everyday use without scratching? Thank you.
