"BlackBerry Messenger 7.0:
As of BBM 7 the BlackBerry Messenger contacts are associated with the BBID (BlackBerry Identity). Backing up through BlackBerry Desktop Software will no longer backup BBM as the contacts are not stored locally on the BlackBerry smartphone. When moving to a new BlackBerry smartphone BBM contacts will populate on the device if associated with the same BBID. "

If you don't have a Backup of your BBM contacts then I doubt from where you will get your contacts as your old device is broken.
Regarding your friend ,there are many possibilites like :
1. If he has done a Switch Device Wizard it will transfer everything from his old device to the new one .
2. If he has a Backup of this BBM Contacts and used BlackBerry Desktop Software to restore his BBM contacts list.
3. Or If he was having BBM 7 on his previous device, as then all of his Contacts are stored with his BlackBerry ID and using the same BlackBerry ID on his new device restored all his BBM contacts.
