8. The wireless mobile device of claim 1, wherein the remote station comprises a peer device relative to the wireless mobile device.

9. The wireless mobile device of claim 1, wherein the remote station comprises a smart telephone device.

10. The wireless mobile device of claim 1, wherein the remote station comprises a computer telephony integration (CTI) server.

11. The wireless mobile device of claim 1, wherein the internet protocol comprises an Internet protocol.

12. A wireless mobile device, comprising:

a wireless air interface which enables both circuit-switched and packet-switched wireless communications between the wireless mobile device and both a circuit-switched telephone network and an internet protocol (IP) packet-switched network;

a user interface which enables a user to specify a remote subscriber identifier corresponding to a remote subscriber;

executable instructions which implement a plurality of functions, including;

(i) sending a first IP packet comprising the remote subscriber identifier to a remote database server via the wireless air interface and via the IP packet-switched network, the remote subscriber identifier to indicate an entry in the remote database containing an IP address associated with the remote subscriber, the IP address indicating where a remote station associated with the remote subscriber can be presently reached via an active 1P connection;

(ii) receiving from the remote database server via the wireless air interface a second IP packet comprising the IP address associated with the remote subscriber; and

(iii) establishing, using the IP address associated with the remote subscriber, a bidirectional and interactive multimedia messaging communication session for effecting transmission of textual characters entered by the user of the wireless mobile device and at least one additional media type to the remote station associated with the remote subscriber via the wireless air interface and the IP packet-switched network;
