This is something which I would also like to do. Maybe I'll explain why so that you understand better. I have a data plan for my cell phone: 10 gigs a month, up to 3.6Mbits/s download (HSDPA). Since it is tied to my SIM card, I can do the following: -use bluetooth to connect the N810 to the Net via the phone -use bluetooth to connect my Macintosh to the Net via the phone -get the SIM card out of the phone, put it in a wireless router (about 200€) and be able to connect the Mac and the Nokia at the same time (and not be able to receive phone calls on my mobile number for the time that the SIM is in the router). So: YES, being able to use the Nokia (or recycle the old 770 I have lying around) to distribute the Internet connection by wifi as soon as my phone is in bluetooth range would be great. Ideally, I would leave the 770 at work: as soon as I am there (with the phone), the 770 connects via bluetooth and all the devices I have with me get a wifi connection. All this with a single SIM card. I know that battery life will be terrible, so I will have to keep everything plugged in. No big deal.
