I am trying to find a copy of the circular logo on the back of all ipods and iphones. It is the one that has a circle with a check mark in it. I know the other logos are FCC certification logos, but when I tried to find this one I could not find it. Of course I am just assuming this is another certification stamp, so if its not that may be why I'm having trouble finding it. if anyone has a good image of this, or can at least tell me the proper name/use of it, it would be greatly appreciated.
