weird icon
I have a weird icon on my ipad "desktop." It is a grey gridded square with an X through the middle and a series of concentric circles superimposed over that. If I press and hold it down, it will jiggle, but it doesn't have an X in the corner that will allow me to delete it. It doesn't seem to be anything I can open. Any ideas what this is and/or how I might get rid of it?
