Why are there separate sound files for PIN messages, Level 1 messages, and BB Messenger messages? Aren't these all the same kind of message? When I go into my sound profile, "message" is a separate list from "instant messages," and that makes sense for things like AIM or GoogleTalk, but why BBM? Am I wrong in thinking that the BBM new message sound is for the same thing as a PIN message? When I set them all different, only the one for BBM new messages plays. When would the PIN sound ever play, then?
