Hi, I have had this Blackberry 8703e for about a year. Recently a new icon started appearing when I lock the keyboard. At the very top center of my screen, the symbol of a little white square with red stripe on top and dark mark in its middle appears when it is locked. Also there is a number beside that icon. At first it was a 1, then a day or so later it was a 2, now it is a 3 since about a week ago. So what I am seeing on the top center, right between the time and the signal strength, when the keyboard is locked is the number 3 on the left of the little white square with the red bar on top. It all goes away the second I unlock the device, and appears immediately when I click lock again.
What is it trying to tell me? How do I clear it?

The white/black/red icon looks a lot like a miniature version of the icon for "calendar", but I am not sure it's the same because it's much smaller. All I know is its the same color scheme and general shape. But it only appears when I lock the keypad, and I don't have anything on my calendar,so I can't see a connection there.
