The method may include accessing by a first wireless handheld communication device (WHCD), a list of devices authorized to access a second WHCD. The list of devices may be maintained by a centralized communication device that facilitates communication between the first WHCD and the second WHCD. The first WHCD may not be paired with the second WHCD. A communication link may be established between the first WHCD and the second WHCD via the centralized communication device, if the list of devices authorized to access the second WHCD comprises an identifier (ID) of the first WHCD. Authentication information of the first WHCD may be communicated to the centralized communication device, prior to the accessing by the first WHCD of the list of devices. The accessing by the first WHCD may be authorized based on the communicated authentication information. ## Claims ### Claim 1 A centralized communication device within a network, comprising: a memory maintaining a plurality of authorized device lists, each of the plurality of authorized device lists being unique to a respective one of a plurality of wireless handheld communication devices and each of the plurality of authorized device lists containing identifiers of one or more devices authorized to access the respective one of the plurality of wireless handheld communication devices;
