I have the Pearl... and when I am in Messenger, I hit add a contact, and I go to the Use Once, it goes right into an e-mail, I don't have the option for a PIN, can and how can I change it to PIN?
Add the PIN number to the contacts name in your address book. Then when
you try to add a contact it should prompt you for by e-mail or PIN. I think it
will take you to your address book to find the person from there.
