I have some questions
Do you know the company bebeme they specialize in change the PIN code for the BlackBerry
Question here
What is the credibility of this company?
You cannot change the PIN on a BB. It is illegal to do so and is not discussed on this Forum.
But I do not think BeBeMe changes your PIN. It appears to create one way to contact you via some alpha numeric address. Interesting concept, but not sure how it works.
