I dropped it and the battery fell out, then I put it back in everything was fine and still is other than this new icon that I can't figure out what it is. It looks like a balloon that would appear when a cartoon was saying something in the Sunday comics and there is a number 1 next to it. It's not a mesage icon or voicemail icon or alarm icon. I can't find any documentation saying what it is.

Never mind, found it. It's a BB Messenger icon. Whats weird is I un-installed it and it was still there. After taking the battery out and booting up again it was gone.
