    Today when I was taking my uMB out of the sleeve, I noticed a small dark grey area that looks almost like a burn mark. It is on the battery cover where it meets the side casing. Its small (about 3-4mm) but I have no idea how it got there. It wasn't there last week. It looks like the aluminum has corroded or worn away or something. Has anyone seen this before? What can I do?

    i tried but it just showed up as a blurry grey spot. All i have is my isight. I looks like whatever would be under the silver, but its in a place that would be really difficult to scratch. And its not a scratch, more like a spot. Its on the part that curves upward against the side so it doesnt touch anything either.
