also for modem script, i chose sprint pcs vision but i also think you can choose bluetooth modem,make sure the choice to show modem status is highlighted
8th: Now you will see a little phone icon on the top right of your screen,click on it and open internect connect ,then click bluetooth,then click connect....
make sure you shut down internet explorer on your phone before you click connect,
if this doesnt work the first time just end all programs on your treo and try it again,or take the battery out and put it back in.
Dont forget to turn off "make phone discoverable" after you pair up your mac and the treo
This hack comes in real handy when you're on the road,in a place where there's no wifi or just dont want to spend extra for internet when you already have it on your phone.The connection speed is pretty good considering that you're connected over bluetoooth. If you would like to share internet over a Usb,you will need some software called the Missing Sync,which also lets you sync your address book.a simple google search will pull that up.
It can be done with blackberrys and a bunch of other phones also.
