Assuming you bought the PB, what you have to do is transfer ownership to him. To do this refer to the following Knowledge Base articles. KB26694, KB24062, KB24157 and KB26361. It is reassuring that RIM is taking these steps to protect legitimate owners. Once thieves realize that they cannot use a stolen PB, maybe they will stop stealing them. Don't take offence at what I just said. Just realize there are many people who have their cell phones and other electronics stolen.
