A system of synchronizing multiple devices utilizing a host system. In one embodiment, the present invention first synchronizes a first device with the host system. Next, the present invention synchronizes a second device with the host system. In so doing, the second device receives all changes which were entered directly into the host system, along with changes from the first device as of the last synchronization between the first device and the host system. If desired, the user may then synchronize the first device with the host system to get the changes from the second device. One embodiment of the present invention allows for any number of devices to be synchronized in this fashion, without having to connect the devices together for a single synchronization. Another embodiment of the present invention allows two devices to perform a pseudo-synchronization process. The pseudo-synchronization process allows the two devices to share recent changes with each other immediately, without the use of the host system.
