You don't say what kind of 3B2 you're talking about.  Maybe it doesn't
matter.  I left AT&T at about the time the model 600 was about to come out.
Anyway, with at least the 300, 310, and 400 the NVRAM (where the firmware
password is kept) is maintained by a battery.  This was fairly easy to
locate and was connected to the system board by a couple of wires with
a connector at the system board end.  If you remove the cover, you can
get to the battery and the connecting wires.  Remove them from the board
for a minute (less time will probably work).  Replace them with the same
orientation!  Now, you have a "virgin" NVRAM.  The default firmware
password will work just fine.  Good luck.  Have fun!
