6. The apparatus of claim 5 further comprising a wired to wireless gateway where the wired to wireless gateway is communicatively coupled with the at least one communication device and the wired to wireless gateway is communicatively coupled with the external server, and the external server communicates a request for a direct connection with the at least one mobile communication device to the relay server module, and the relay server module coordinates a direct connection between the external server and mobile communication device, and where the mobile communication device and the external server perform a peer-to-peer exchange via the wireless gateway using the direct connection.

7. The apparatus of claim 5 wherein the service gateway controller instructs the at least one mobile communication device to terminate the session with the service gateway and establish a session with the external server via a second service gateway.

8. An apparatus, comprising an IMS compliant mobile communication device, the mobile communication device comprising:

a mobile redirector that is configured to receive and unpackage packaged emails; and

a service client that is configured to perform a peer-to-peer IMS session with an external server that resides outside an IMS network.

9. The apparatus of claim 8 wherein:

the external server is an email server;

the mobile communication device is communicatively coupled with the external server;

the external server comprises a server redirector that is configured to receive an email addressed to a computing device, package the received email and send the packaged email to the mobile communication device.

10. The apparatus of claim 9 wherein the mobile communication device communicates an email to the external server and the external server packages the email so that it appears to a recipient that the email came from a computing device other than the mobile communication device.

11. The apparatus of claim 8 wherein:

the mobile communication device is communicatively coupled with a service gateway controller and the service gateway controller is communicatively coupled with the external server;

the service gateway controller is communicatively coupled with at least one service gateway, and the at least one service gateway is communicatively coupled with the mobile communication device and the external server;

the mobile communication device establishes a session with the service gateway controller using IMS signaling; and

the service gateway controller assigns a service gateway from the at least one service gateway and directs the mobile communication device and the external server to establish a session via the service gateway where the service gateway is the assigned service gateway.
