I have been successfully using an Intel MacBook Pro with a Cingular LG CU500 (using bluetooth) and a Cingular data connect plan to connect to the internet. I followed Cingular’s directions from their support web site, but it required typing a modem init string every time I connected. The directions involved using the null modem 115200 script, so I simply modified that script, added the commands that I was typing every time to connect, changed to connect rate in the script and saved it as “LC CU500”. It worked and a few speed tests have given me download speeds of 418-579kbps and upload of 135-141kbps (in the Dallas, TX area). Here is my modified modem script (save as a text file named LG CU500 in folder /Library/Modem Scripts):

and here are the directions to setup the LG CU500 with Mac OS X:

( Cingular’s instructions read “Check Connect using a terminal window, and click on OK.” but if you use my modem script, ‘Connect using a terminal window’ should be unchecked )
Click on the Bluetooth Modem tab.
From the Modem drop down menu, click to select LG CU500
( Cingular’s instructions use Null Modem 115200 )
Uncheck Enable error correction and compression in modem.
Uncheck Wait for dial tone before dialing.
Click on Apply Now.
Click on System Preferences, and then click on Quit System Preferences
Making the connection
From here, Cingular’s instruction didn’t quite work, but using my modem script, you can just open internet connect, select bluetooth, and click connect, and you should get connected, but here is cingular’s instructions:
On the mac, click on the Phone/Modem icon, and click to select Bluetooth.
Click on the Phone/Modem icon, and click on Connect.
Once the Terminal window opens, type
at+cgdcont=1,”IP”,”isp.cingular”, and press the return/enter key.
Once OK appears, type atdt*99# and press the return/enter key.
Once CONNECT appears, then click on Continue.
You will now be connected to the Cingular GPRS service
Good Luck!
