HTC Droid Incredible

Hey guys, I have a new weird symbol/icon in my notification drop down that ive never seen before. its set up like a fraction with the top looking like a capital F without the small "arm", with the part going left to right longer then the top to bottom part.there is a slash like a fraction,although it goes on angle(from 10 to 4 like on a clock) and then on the bottom is a solid white circle. If anyone knows what this is please let me know,Thanks
