So I'm on my second iPhone 5. The first one I got on launch day, and since there were no cases out I used it without one. The next day it fell on concrete and the metal band was dinged to the point where the silver aluminum was showing, and there were a few scratches. Since then i put a black bumper on it. Thankfully, my iPhone developed some problems and after a trip to the apple store I got it replaced for a brand new one. This one currently has the bumper on it. Like a lot of other folks, I think the iPhone 5 looks amazing without a case, but in order to keep it in pristine condition like I like my things, I have had to put a case on it. My question is, if I put ghost armor on it, will that be enough to protect it from dings and scratches from drops? Or will a case still be necessary?
