Rodney, you refer to problems and ask what can be the cause, but you don't describe the problem. No one can help if you don't state the problem.
As far as the PIN, all BlackBerry devices have had a unique PIN hard coded on the device. This identifies the device. PIN messaging is peer to peer, BlackBerry handset to BlackBerry handset, and functions as an alternative/backup to email. BBM was introduced later, providing a chat feature, but uses the handset PIN as well.
A beneficial feature of the PIN nowadays is that you are not sharing a mobile number or email address with a new contact unless you want to give it. When you get a new device the system updates your contacts automatically with your new PIN.
