So guys, I purchased my iPhone 5 this Saturday and, having not dropped, banged, or anything of the sort to my phone since then, I noticed this gap between the glass pane at the top of the phone's back and the bezel surrounding the device.

I am so completely OCD about things like this, and so everytime I pick up my phone, I have to look at it... I hate it. I have looked at several other white iPhone 5s in person, and none have this issue. I am debating wether to take it to the Apple Store or not.

Also, the sleep/wake and volume buttons feel extremely loose and they were not on either of the other devices I held.
