Even if you can surf on the Internet from your phone and your bluetooth connection is ok you CANNOT access the Internet using your digital modem if you didn't subscribe the option with your operator.
Of course, this one is able to distinguish between a flow coming from the phone and a flow coming from a external device through the modem: that's the phone that makes the difference. If you were able to modify the firmware in order to make the phone not to distinguish between these 2 types of flow you would'nt have to subscribe an new option. But, since the price (by volume in general) is the same for both flows it would be unuseful to work this way.

Conclusion: call for you phone operator and ask him to enable the option (sometimes called "pocket data").
You've got the chance of having a phone that works in bluetooth (the 6630).
On my side, I have a 6230i - EDGE compliant phone - for which the Bluetooth doesn't work well (it's a welle known problem !).
Imagine, I have both Nokia equipments, the 6230i and the 770, and it's not possible for me to access the Internet whereas it's working perfectly well with a Siemens S65 !
But the S65 is not EDGE compliant so surfing is slow (~20 kbit/s).
