Mine died in less than a week. I took it into the Apple Store and the employee first asked me if I had an appointment at the Genius Bar. When I said no I was just in the mall shopping so I thought I would just walk in. He said normally I would need an appointment. But because he didn't want me to wait over an hour for the next appointment. He plugged the cord into a computer that was sitting right there in front of him and saw the cord was dead. So he replaced it for me.
