Now, first you have to get the TCP/IP-APN stuff setup. To do that, go to “Settings” -> “Options” -> “Advanced Options” -> “TCP”. There are three fields: APN, Username for APN, and Password for APN. Fill them out like so:

APN: wap.cingular
Username for APN: WAP@CINGULAR.COM
Password for APN: CINGULAR1

As far as I know they are case sensitive. It’s also strange because I’ve seen other settings out there, but they have not worked for me. I checked to make sure these were working by using midpssh. When the APN settings were wrong, I kept getting “WRITING: TUNNEL FAILED” from midpssh.

Now, on your Mac, the first step is to install the modem scripts. I can’t remember where I found them, I think it was here. At any rate, I put the file here, so I can find it later.

As per the directions, unzip into Macintosh HD:Library:Modem Scripts

After that you can pair your phone, if you haven’t done so already. The Bluetooth valet/wizard thingy may ask you if you want “access the Internet with your phone’s data connection,” then you can choose the phone model and stuff. The trick is when you put in the phone number, username and password, use the APN settings. For example:

P.S. My phone was recognized as a USB modem as well, however I couldn’t get it to connect — no idea why.
