what I did was created a batch file:

save this file below in usr/bin call it vnc

------------------
#!/bin/bash
dbus-send --print-reply --system --dest=com.nokia.mce /com/nokia/mce/request com.nokia.mce.request.req_tklock_mode_change string:unlocked

x11vnc -timeout 20 -bg -grabkbd -cursor X
--------------------


line 2 unlocks the phone
line 3 starts x11vnc
- times out in 20 seconds if vnc connection hasnt begun
- bg will start the vnc in the background
- grabkbd will lock the keyboard (will also not let the phone blank out!!!)
- cursor X will show a cursor

so everytime you want to want to vnc to your device.
either open x term or telnet to it and type vnc.
