I received my preordered iPhone 4S when they came out a week ago. Starting yesterday, the volume up button seems to be shorted out intermittently. I first noticed it when using the camera function and it kept taking photos without pushing the button. It is also taking the volume up to max occasionally when listening to music or turning up the ringer volume to max. So, any possible quick fixes that anyone might know of short of a trip to an Apple Store? The closest for me is an hour away and I'm concerned that they won't be able to duplicate since it is an intermittent problem or that they won't have one in stock to do an exchange.
