Hey Guys; I have been searching high and low for a defintion of system notification icons, and I cannot seem to find it ANYWHERE. So I apologize for asking such a silly question, but anyways... Ever since I updated to 2.3.3 (gingerbread I assume) a new notification icon has been present, three white verticle waves. I have no idea what it means! What it my droid trying to tell me??? Thanks in advance!
