There are inbuilt generic IrDA/Bluetooth modem drivers on the iPAQ. You don't need any Nokia software.
Just pair the phone and iPAQ in Bluetooth Manager and then if you go into Connections under Settings you can set up a dial up connection in there using "Bluetooth Dialup Modem". I recommend you set the baud rate to at least 57,600 if not 115,200 Kbps. This applies whether you are using GPRS or HSCSD.
You also need to go into dialling locations and then dialling rules and set them as follows:
Local number = G
Long distance number = FG
International number = EFG
Getting nokia 6310i modem software onto my bluetooth ipaq
I know that this is going to seem like a dumb question to the more technical people... but. I want to try and use the HSCD / GPRS modem functionality of the 6310i. How do I get the modem set up onto the Ipaq as I have no way of connecting a CD drive and I can't find the system files to download from the web.
Slight postscript to this my laptop has IR but not bluetooth so when I use the CD that came with the phone it will not let me install bluetooth software
