Method, system and apparatus for selective application access and synchronization

1. A mobile communication device comprising:

a first application operable to communicate and synchronize with a remote application operating on an external computer; and

a second application operable to communicate and synchronize with the remote application;

wherein the mobile communication device receives a user's identification of a preferred application selected from one of the first and second applications, and uses the preferred application to synchronize the mobile communication device with the remote application.

2. The mobile communication device according to claim 1 wherein the first application is operable to communicate with the remote application via a wireless communication link.

3. The mobile communication device according to claim 2 wherein the wireless link is selected from a cellular link, a WiFi link, a Bluetooth link, a Zigbee/IEEE 802.15.4 link and an infrared link.

4. The mobile communication device according to claim 1 wherein the second application is operable to communicate with the remote application via a wireless communication link.

5. The mobile communication device according to claim 4 wherein the wireless link is selected from a cellular link, a WiFi link, a Bluetooth link, a Zigbee/IEEE 802.15.4 link and an infrared link.

6. The mobile communication device according to claim 1 wherein the first application is operable to communicate with the remote application via a wired link.

7. The mobile communication device according to claim 1 wherein the second application is operable to communicate with the remote application via a wired link.

8. The mobile communication device according to claim 1 wherein the external computer is disposed within a packet-switched network comprising a plurality of application servers.

9. The mobile communication device according to claim 8 wherein the packet-switched network is one of a local area network (LAN), a wide-area network (WAN), or a metropolitan area network (MAN).

10. A method of synchronizing data between a mobile data communication device and a remote application operating on an external computer, the method comprising:

receiving a user identification of a preferred application selected from a first application operable to communicate and synchronize with the remote application and a second application operable to communicate and synchronize with the remote application;

storing data associated with the preferred application on the mobile communication device;

establishing a connection with the remote application; and

sending the data associated with the preferred application to the remote application over the established connection for synchronization with the remote application.

11. The method according to claim 10 wherein the established connection with the remote application is a wireless communication link.

12. The method according to claim 11 wherein the wireless communication link is selected from a cellular link, a WiFi link, a Bluetooth link, a Zigbee/IEEE 802.15.4 link and an infrared link.

13. The method according to claim 10 wherein the established connection with the remote application is a wired connection.

14. The method according to claim 13 wherein the wired connection comprises one of a USB connection, an IEEE-1394 connection, a PTSN connection, an RS-232 connection, and an Ethernet connection.

15. The method according to claim 10 wherein the external computer is disposed within a packet-switched network comprising a plurality of application servers.

16. The method according to claim 15 wherein the packet-switched network is one of a local area network (LAN), a wide-area network (WAN), or metropolitan area network (MAN).
