weird icons !

okay so i have an icon on the top of my blackberry where the "new message' icons and such show up. It's a black circle with a white ring around it with an arrow pointing down diagnally to the left. it's obviously saying i have one of somthing but i dont know what i have one of. i've gone into my messages, saved messages, emails, blackberry apps, bbm, EVERYTHING i can possibly think of. Can anyone help me with what this icon is?

you need to upgrade an app

and mark all your messages as opened

That's from the apps store, one of the downloaded apps has an update available
