| | Re: Odd email
They send out these "blast" emails with tips/tricks to whatever carrier-based email account you have set up. I don't use my sprint.blackberry.net account for anything, but all that stuff from BlackBerry comes to that account. If Orange knows you have it then RIM knows you have it. These emails probably go from RIM to the carriers, and from there they get pushed out to all the relevant devices registered on the network.
