Bluetooth Modem under OS X

Thanks to ggoodale @ BlackBerry Forums
1. Download the script from here. Please Right-Click and Choose ‘Save As’.

2. Copy the script into /Library/Modem Scripts.

3. If you’ve already paired your device with your Mac, open Bluetooth Preferences, Select your device from the list of devices and press ‘Configure…’. (If you haven’t, choose ‘Set up Bluetooth Device’ – the following dialogs will be shown after you’ve paired your phone with your Mac. Make sure your Pearl doesn’t require a password for your mac to connect to it – the ‘Trusted Connection’ option for the pairing should be set to ‘Yes’ on your phone, not ‘Ask’.)

4. Make sure ‘Access the Internet with your phone’s data connection’ is checked. Also, make sure ‘Use a direct, higher speed connection’ is selected. Click Continue.

5. In the Modem Script pulldown on the following screen, Select ‘BlackBerry 8100’ (or your device). Use the following settings for the other fields, then click Continue:

 * Username, Password: leave blank
 * GPRS CID: *99***1#

6. Open the Internet Connect application. Select the Bluetooth icon at the top. Under Phone Number, put your APN (for T-Mobile and the BlackBerry Unlimited plan, I use, for Cingular it’s “wap.cingular”). Type a username and password (I use guest/guest, for Cingular you’ll use “WAP@CINGULARGPRS.COM” as the username and “CINGULAR1” as the password) in the appropriate fields.
