do you have usb modem installed on your treo? I just have to click usb modem on my treo and use bluetooth then just hit connect bluetooth via mac (after of course the phone has gone through bluetooth sync) and it works. I use the #777 to dial then
mynumber@vzw3g.com as user name and vzw as password. I use the mobile stream CDMA script (comes with usb modem) and for ppp configuration i have both compression and echo packets unchecked, let me know if this helps
*If you dont have usb modem installed on the treo once it is installed you then need to bluetooth sync again in case it did not find access internet from phones data connection, and also you will need to do that to make sure that there is a serial port created.
**If you are wondering where to get the script for the modem it comes with USB modem.
