Well - having got the mac mini - time to get bluetooth net access running - just for the fun of it.
To get bluetooth internet access running for my S700i Sony Ericsson I found the following two places useful
For a tutorial: http://www.crackistan.com/2004/11/connect-gprs-via-sony-ericsson-k700i-mac-os-x-bluetooth/
For the Sony Ericsson modem scripts http://www.taniwha.org.uk/
For Telenor - the CID of the downloaded internet connection was 1.
So I used:
Service Provider: Telenor Account Name: internet Password: seems to work with either empty or "guest" Telephone Number: blank
Configure IPv4: Using PPP
Modem: Sony Ericsson GPRS CID1 +CGQREQ Enable error correction and compression in modem: Checked Wait for dial tone before dialing: Checked Show Bluetooth status in menu bar: Checked Show modem status in menu bar: Checked
