If there isn't any visible damage to the iPhone itself, I'd suggest sending it back to Apple -- or if you have an Apple Store nearby that would be my first suggestion. From the photo, it's hard to tell if it's a scratch, chip or some debris floating around on the inside of the phone. iPhone 5 parts are difficult to find right now... it would also be a difficult part to replace. Try Apple and see what they can do for you.
