If you have to resort to guessing, try friends' birthdays, or ask if he remembers any numbers in it.
If the phone no longer gets service, or even if it does, you can go with him to a Verizon (or Cinglular, whatever the carrier is) and prove that you own the phone, and they'll unlock it for you. If the phone has been deactivated you may not even need to do that.
