That won't do anything, if you don't have an account setup yet!
You bought your BB used, and the previous user has not removed the PIN of that BB from his account. Call and ask them to do so, or call your carrier yourself and explain you bought the BB used, and would like to have the PIN removed from the previous account. They should and normally will if you ask nicely... they don't have to.
