Basically there been a thread like this before. The guy didn't reply once and at the end he just posted they did a refund for him at the Apple store. The issue was that when he presses the corners of his iPod (usually the bottom), you could hear a tiny click as you would hear when something sticks and unsticks from glue. What is the problem with that? Basically none, the iPod works as is should but its one of those things that annoy you. I basically have the same thing, when I press the corner carefully with a fingernail, I can see it flexing down past the silver backing. I asked on apple forums and they just said "take some engineering classes, you are an idiot". The guy at Apple store made up some bullsh*t that they can't help me right now because I need to set appointment at apple.ca (and you can't). The showcase models at the Apple store generally are stronger at the corners and don't flex that much. Do you think this is something big or no?
