Not sure what happened but my daughter cannot get her headphones to fit in the headphone jack. It was working fine one day and the next day she could not get them to fit in. We sent it to Apple and they determined the damage is from an external cause so they won't fix it for free. I have tried over and over to "force" the headphones in but still no luck. I cannot see anything down in the actual jack...only the white sensor. I have used a toothpick to see if there was anything in there and couldn't find anything. Please help.
