I don't know anything about BBs but my dad is visiting and has one for work, a Curve 8330. A few times since he's been here it has buzzed and he can't figure out why. There is an icon on the screen that he does not recognize, it looks like a gun sight (a circle with a plus in it) with a couple of semi circles going out from it, like a volume level might be. Can anyone tell me what that icon is and if it is related to the BB buzzing? Thanks!
