Hey guys, so I've noticed that there is a peculiar gap at the top of my phone (and not on the bottom). It is fairly small, but visible (at least to me) when you notice it and then you can't unsee it... Dirt and pocket lint has accumulated in the space and I have to use a piece of paper to clear it out every day. Has anyone else experienced this? I want to go to the Apple Store to see if they would swap it out for me, but with supply of the 5s being what it is, I would be worried they would turn me away.
