There are three locks:
SIM lock: The lock on the SIM card (easy).
IMEI lock: The lock on the cellphone itself (only Bongo or original carrier can do this)
PIN lock: The lock on the BlackBerry network (unfortunate common "GOTCHA!")
BongoWireless only unlocks SIM and IMEI, to the best of my knowledge (correct me if I am wrong). You have to get the BlackBerry properly cancelled at the original cellphone company, before activating it at the new cellphone company. BongoWireless did their job - they completed the other locks for you. It's now your job to finish the remaining unlock.
RIM has PIN lock on the BWC if the PIN is already registered with another carrier. That needs to be de-registered by the original carrier. Find out where this BlackBerry was originally used on, and call the original carrier to get it removed from their system. This may require involvement from the original seller.
PIN lock can even be a problem within the same carrier -- when transferring the BlackBerry to another subscriber.
For carriers that refuse to unlock (i.e. AT&T), it's easier to masquerade as a person who wants to sell the 7780 to another AT&T subscriber, and you simply need to make sure that "YOURACCOUNT@blackberry.net" is properly deleted. (This should automatically unlock the PIN, don't use the word "unlock" when talking to AT&T representatives.)
In Brief: If the old blackberry.net original email account is not deleted, the BlackBerry cannot be used by anyone else. That's called the "PIN lock". BongoWireless does not do this (to my knowledge).
