then set the vendor to research in motion, and the model to blackberry IP modem (not sure if your carrier is GSM or CDMA) and play around with the CID number. i'm not sure if you've already tried that or not. but it should work. if you've already tried this let me know. i've been able to successfully use bluetooth tethering without any extra applications on mac OS's 10.4,10.5, and 10.6. although i have the extra tether plan. if you don't then i figure they caught ya.
hope that in some way i helped here.
