bb pin release from tmobile?

[crackBerryTour]

I recently bought a TMO 8520 complete package but want to sell it or return it to the store... but i don't want people sending BBM's to my pin anymore.. how do i go about getting the pin released...and if it does get released does this mean BBM will never work on the device again...or will the buyer get a new pin?

The PIN will always stay with the BB. The new owner will have the same PIN as that BB...there's no "new" one or anything.

Just call up T-mobile and get to BB tech department. Tell them you need to sell your blackberry and will need to the PIN released to do so. They'll help.
