I have a Nokia 6310i & have just got a TDK PCMCIA Bluetooth card so I can use the bluetooth connection between phone/PC for GPRS internet connection. I can pair the devices but the connection keeps dropping. I suspect it is the phone because I also have a Plantronics M1000 Bluetooth headset which has the same problem when paired to the phone. Plantronics told me it is the Nokia firmware (currently 5.22) which is the problem. I am wondering if anyone else has had problems with a 6310i? I am being sent a new phone with 5.5 firmware so hope this will fix the problem. I also read that the Nokia smartsuite needs 5.5 to work with Bluetooth so suspect a bug in the Nokia that they haven't come clean on.
