Sorta... but not quite as I understand it. When you send a service book from BWC it sends a "notification" to the BB infrastructure to send the service book to your handheld. The PIN etc are all in that notification because your PIN is associated with your BWC account. All these notifications handled by the BB infrastructure which, from what I've read here, not too many people will ever be able to get much information about.
Roll on Friday... 1 hr left of work!
