Fogive me if I am in the wrong place but as I looked into the issue myself I aw that programmers on BB site were dicussing issues like this.
Since I got my BlackBerry it is working fine but I am getting about 20 of these messages a day:
<<This message is used to carry data between the BlackBerry Handheld and an associated server. Please do not delete, move or respond to this message - it will be processed by the server.
What are they and is this "normal". Blackberry support stinks otherwise I'd go there..............
