How to use Mobile as modem using Bluetooth?

Hi,
I have a Nokia 3110i set. I bought it 2 months ago. I use my USB cable, to use it as EDGE Modem. But recently I have lost the cable and my USB port is also giving me some trouble. So, I don’t want to buy another cable.
I want to use it by using Bluetooth. How can I do that?
Please help.
Thanks!
