A computing device adapted for storing unique device data in an address book stored in a memory comprising:

• a communications subsystem configured to receive a message including a public
• user identity and an instance identifier for the unique device;
• and
• a processor, wherein the processor is configured to:
• determine that the public user identity exists within the address book and the instance identifier does not exist within the address book;
• and
• store device capabilities of the unique device,
• wherein the instance identifier is selected from the group consisting of:
• a medium access control address, an international mobile equipment identity, an electronic serial number, and a personal identification number.

A non-transitory computer readable medium storing a computer program product, which when executed by a processor of a computing device is configured to:

• receive a message including a public user identity and an instance identifier for the unique device;
• determine that the public user identity exists within the address book and the instance identifier does not exist within the address book;
• and
• store device capabilities of the unique device,
• wherein the instance identifier is selected from the group consisting of:
