I bought a launch day iPhone 5 and recently I noticed that there is dust inside the camera lens, which renders noticeable spots when I take photos against solid color backgrounds. I've taken pretty good care of the phone so not sure how something like that would happen. I didn't buy AppleCare but was wondering if anyone has had success with returning and getting a new one at the Genius Bar? It's not easy for me to make a trip to the Apple Store so if it's hopeless, I probably won't bother. Any advice appreciated, thanks.
