Has anyone else noticed that their new iPhone is getting a dent around the headphone jack? On my 6+ I noticed a small Mark the other day. I believe the Mark was caused by putting the headphone cord into the socket in my car. The head of the cord lines up perfectly with the mark. A close friend of mine with a 6 has experienced the same thing, only worse. He has an actual small dent just from putting headphones in. Has anyone else noticed this? If it's not a dent, it might be a small mark in the anodized aluminum.
