Hi i just purchased my first BB and i was worndering how do i add new pin to my 7100

You can't add a pin to a blackberry at all, each bb has its own unique pin. Look under Options, Status to find yours....

Or do you mean a PIN for another user? If so, there's a field for it under their contact in the BB address book. Strangely enough, there's no field for it in Outlook so PINs can only be added directly into the BB.

Thanks a lot
