Should work. If you notice, in the control->panel->Programs feature there's a modem driver installed together with the NPS or ActiveSync.
Bluetooth and usb cable should work, maybe now, can share internet using phone wifi also... maybe..

Samsung pc studio have the internet sharing feature... Just explore the software... Make sure you are connecting to it using usb or bluetooth.

I think it's in the Networking Wizard (Manage Internet Connections)

thanks, all can be done

just that, it should be able to sync via bluetooth right?

also anyone know how to monitor/check data usage? afraid overshoot the limit provided by the telco

how u do that ya?im still stuck lor..i m try search the device and after that got 2 device
1 is GTi8000 (connected)
2 is Windows mobile base device (connected)

but i canot press the connect icon. why pls help...     

not sure the reason why you dont wish to upgrade but what i know is that OmniaII is meant to work on Winmo6.5 and only with Winmo6.5 it will really perform fully... if you using 6.1 is like a underpowered car if you understand what i mean..

personally feels that 6.5 is much better after using 6.1 for one week plus.. 6.5 is damn way faster and less problem compare to 6.1

Good luck in making your choices
