I have a voice mail notification that won't go away. I already "clicked" on it to go to my voice mail and I deleted all my messages. Yet it remains. I have had other notifications but when I click on the "clear" button, it only clears the other things in there but still leaves the voice mail one behind. Any clues?? I tried restarting the phone by turning it off, and its still there. I guess I could try removing the battery next.
