Use your blackberry as a bluetooth modem
Be aware that you may be charged on your wireless phone bill for data usage. I take no responsibility for anyone who incurs charges by following these directions. You have been warned.
1. On your BlackBerry, turn bluetooth on and make your phone discoverable. This may vary with each model, for the 8130 this is done by using the Set UP Bluetooth App.
2. On your MacBook go to System Preferences, and click on Bluetooth under Internet & Wireless.
3. Click Set Up New Device.
4. Select your BlackBerry and click Continue.
5. Enter the passkey into your BlackBerry.
6. Set Phone Vendor to Generic, Phone Model as Dialup Device, and User Name, Password, and Phone Number as required by your wireless carrier, then click Continue. The next screen should confirm that all is set up correctly. Exit if it does, if not go back and see if you missed something.
7. In System Preferences go to Network, and connect the Bluetooth DUN to use. Select the "Show modem status in the menu bar" check box to connect and see the modem status from the menu bar. You can also click Advanced for more modem options. Once you have completed the set up procedure, you need only turn you BlackBerry bluetooth on, and connect to the Bluetooth DUN as shown above.
Note: This tutorial was preformed with a MackBook Unibody, Snow Leopard 10.6.1, and a BlackBerry Curve 8130. Your may have to make adaptations depending on your devices.
