There are several choices in the "advanced" tab. Either RIM cdma or generic cdma will work, you may have to try each until you see what works for you.
You also need it provisioned on your account or you won't get in unless you use a third party program like TetherBerry (in beta now). If you have it on your account, you can download Verizon Access Manager. Tethered is faster than BlueTooth, but it is pretty convenient...
Hmmm.... try VZAccess Manager for the Verizon Access Manager program. Works pretty good. Probably comes with that. Or you can hunt for(or wait for) BB Desktop Manager for Mac, due out tomorrow....
