If it is NOT a corporate BB, and it was bought with an IT policy on it, you will have to search the forums for a solution to removing the IT Policy.
Good luck and welcome.
NJBlackBerry is right.
The only way to get ride of the IT Policy is to wipe the handheld and activate it on another BES. Once it is on the name make sure the the new IT Policy that gets send to the handheld does not have password required. Once the new IT Policy has been applied you will be able to remove it from the Options > Secuirty from the HH.
