This post by "sirforce" on Crackberry Forums describes how to configure Mac OS X.5 to get onto VZW's EVDO network using a Blackberry 8330 and Bluetooth. I am reproducing it here in the interest of spreading the knowledge, and in case the forum should disappear.
1. Added tethering your Verizon service plan for an additional $15/month.
2. Pair your phone with your Mac/MacBook via BlueTooth This worked on my MacBook Pro and Mac Pro workstation.
3. Add a new dial up modem in the networking preferences panel-
Telephone Number: #777
Account name: email@example.com (change the number to your verizon mobile #)
3a. Under advanced options:
Model: Verizon Support (PC 5220)
Check Enable error correction and compression in modem
Dial Mode: Wait for dial tone before dialing
The remaining tabs: DNS, WINS, Proxy, etc are all set to default settings no changes are necessary
4. Turn off your AirPort or disconnect your ethernet then press connect to dial up and enjoy near broad band surfing via Verizon -
If you're not on the EVDO network then your speeds will be more "dial up" classic like.
Once connected, your phone should have a notice at the top of the screen "Modem Mode Enabled"
On a side note:
I setup a friends modem without tethering on his plan and once the internet was connected and then attempted to load google.com. The web page that appeared was a verizon page that would allow the addition of tethering to the users account for $15 just by clicking the yes I agree, pretty cool!
