Patent ID: 8260265

Claim:
A primary wireless communication device comprising: a cellular communication system configured to wirelessly communicate instant messages over a cellular communication network; a message storage system configured to store instant messages; a messaging module configured to allow a user to create instant messages, each addressed to a target cellular communication device at a cellular communication network address, to send the messages through the cellular communication system to the target cellular communication device to which they are addressed, to receive instant messages addressed to the primary wireless communication device from the cellular communication system, to store the sent and received instant messages in the message storage system, and to read the sent and received instant messages in the message storage system; a secondary wireless communication system configured to wirelessly communicate with a secondary wireless communication device other than through the cellular communication network; a proxy module configured to receive instant messages from the secondary wireless communication system that come from the secondary wireless communication device, each instant message from the secondary wireless communication system being addressed to a target cellular mobile communication device at a cellular communication network address that is not an address of the primary wireless communication device, and to send the received messages from the secondary wireless communication system to the target cellular mobile communication device through the cellular communication system; and a synchronization module configured to: cause the instant messages that are sent and received by the messaging module to be replicated in the secondary wireless communication device; and cause the instant messages that are received by the proxy module from the secondary wireless communication device to be replicated in the message storage system.
