Is there somewhere i can see what all the icons that show up on the top bar are for?

I'm using the 3d icons, and recently, at apparently random times, but usually when not in a 3G area, i get a random grey circle inside a box to the left of the 1x notification. the box looks just like the Sound icon surround does, but it appears to be empty or has a small circle in it. Can't really tell. I'd take a screen shot, but of course it isn't doing it now.

I'm not sure what it is for, and if i tap it, all i get is the notifications screen.
