Nokia 3650 disconnects after dialing ISP

Question

Using the Nokia IR 6210_8xxx script, I am able to successfully establish a Bluetooth connection with my Nokia 3650, but after dialing it simply disconnects.
I can manually dial the ISP from the 3650 and listen to the handshake.
Prior to installing Tiger, I was able to do a dial-up connection using the Nokia 3650 as a modem.

Thanks Alexander and Stephen — oh that I had found Stephen's link before I got my phone to work, it might have saved me hours of fun, but as I was sitting on a remote Scottish Island, it was only after I got it to work that I could read it.
The Nokia now works perfectly on the UK's O2 service (albeit at a pitiful 9,200) and I even took half a dozen photographs with the phone, transferred them to my iBook, then sent them via the telephone attached to an e-mail.
I never discovered what the problem was other than painstakingly repeating the pairing and bluetooth dial-up settings until both the phone and the computer believed me.
The only small sensitivity I have discovered is that it is completely reliable if I put the bluetooth dongle in the USB socket with the machine switched off, then fire it up.
I know that it is slow using the phone as a modem on the GSM network, but even paying for the extra time involved, it is nowhere near as expensive as being charged at the data rates on GPRS.
