When you upgrade to the new BBM, you’ll find you have access to some new contact categories. There are now contacts and BBM contacts.
Contacts are people in your device’s contacts app who are already using BBM. You can start chatting with these contacts right away, no BBM invite required! This is a great way to discover other people you know who are already using BBM.
BBM Contacts require an invite. These are contacts that you have added to BBM. Only BBM contacts can see your BBM display picture and BBM status updates, and only BBM Contacts can call you using BBM Voice.
