The headphone port on my itouch 3rd gen is loose, so now I have to wiggle my headphone jack around in there until sound comes out of both left and right. Mostly sound will only come through the right side of whatever device I plug into the ipod. I know it's not water damage because it hasn't been near water in all the time I've used it. I think it's just wear from plugging and unplugging. Is this something that can be repaired for a reasonable price at an Apple store?
