I just got mine at Comp USA yesterday. I have a Nokia 6230 w/BT via Cingular. At first the cell phone and 770 would pair well but an error message on the phone told me I had to subscribe to a GPRS service. A call to the data people at Cingular told me that I had to subscribe to their laptop data service. So I was unable to connect via media net as someone earlier had suggested. I'm paying $80/month which is a rip-off but I pay my bill through my office anyways so no biggie. The service is not particularly fast, I would estimate it at half the speed of a WLAN linkup. It is very cool to be connected via BT
