Cingular 2125 to Mac OS X via Bluetooth

The all new Cingular 2125 offers many great advantages, one of which is being able to take advantage of the Cingular high speed EDGE networks. We came across this great how to article with step-by-step instructions on how to tether your 2125 to your MAC via Bluetooth and felt it necessary to share.

The instructions below were tested using an i-mate SP5 smartphone and Mac OS X.4.4. I haven’t tested this on a Windows Mobile 2003 smartphone (i.e., i-mate SP3i), though I’m pretty sure it won’t work.

• Make sure that when you’re setting up your mobile phone’s Bluetooth capabilities within Mac OS X you check “Access the Internet with your phone’s data connection.” If your phone is already paired and you initially forgot to select this option you can find it at System Preferences | Bluetooth | Devices [choose your device] | Configure.
• Download Ross Barkman’s IPAQ PDAs modem script.
• Unpack the archive and place the IPAQ GSM script into /Library/Modem Scripts/
• Go to System Preferences | Network | Show: [Bluetooth]
• Click on PPP Options and make sure that “Use TCP header compression” is unchecked. Click OK.
• Click on Bluetooth Modem and choose the IPAQ GSM script from the drop-down list.
• Disable both “Enable error correction and compression in modem” and “Wait for dial tone before dialing.”
• # Click on PPP. T-Mobile users aren’t required to put in a specific username or password, but apparently it breaks if you don’t put something in both fields. If you’re a Cingular subscriber you’ll want to use the following information:
  Account Name: WAP@CINGULARGPRS.COM (all caps)
  Password: CINGULAR1 (all caps)
• Enter *99# as the phone number. (at times *99***1# may work better)
• Click Dial Now and then click Connect.
