Can you post a little more information about your setup?
i.e. Linux Distro and Version
Version of software and utilities involved.
maybe even a link to which tutorial you used to get as far as you've gotten.
then just a few generic questions.
1.) Are you sure the bluetooth connection is established?
2.) Have you verified that rfcomm.conf contains the BT address of the phone you are using?
3.) Have you adjusted the scripts you are using to reflect the user/pass info required by Rogers?
4.) The 8120 that you said works; is this a device that you have your hands on or is it being verified by another user?
I have a few more questions but knowing a bit more about your setup and method will help.
Thanks and good luck
I can see you...
