I recently have had problems with my headphones not working correctly unless "spun" the correct way. Today I took a look inside the jack, and noticed that the metal band seems to be cracked or broken. If you look around the rim, it goes from a silverish color to a white color, as if half the metal band broke off. There is also a small chunk next to the headphone jack missing. I am assuming the crack within the jack is what is causing this problem. Has anyone had this problem? I am hoping Best Buy or the Apple Store will replace this when I finish college next week!
