Net Access Using an iBook, Bluetooth Adaptor and a Mac?

davesag asks: "How are people connecting to the net using Mac OS X and a Bluetooth phone, such as an Ericsson T68i? I have to buy a new mobile phone today or tommorrow and so far have not been able to find any details on how i would use a mobile phone as a modem with Mac OS X. I have seen plenty of people use their phones with computers running Windows XP but from what i can see no-one makes Mac drivers for the phones. I have seen plenty of apps for synching phones' address books etc, including Apple's own iSync, but none of these options seem to allow the Mac to take advantage of the GPRS Internet connectivity. I am keen to hear other's experiences, or lack thereof with Mac OS X, Bluetooth and mobile net access before I shell out my money."
