What is this system icon that looks like a plus inside a diamond with three curved lines extending from its right side on Samsung? My Samsung Droid Charge has an icon in my status bar that looks like a plus inside a diamond with three curved lines extending from its right side. It is the left-most icon in the right adjusted icons in the status bar of this home screen capture.



What is this icon for? Also, is there a setting where I can remove it?
According to the manual (WARNING: pdf file) for the phone (page 24), it is the GPS icon.
