I have successfully navigated the murky waters of AT&T to identify the process of getting the blackberry tethering to work with my Windows based PC and I wanted to provide a resource for others.
Setting up the Bluetooth Dial up Networking was the easy part, avoiding the PPP 734 Error was the pain. Hint, it had to do with this: AT+CGDCONT=1,”IP”,”wap.cingular”. I know, it looks Greek, but it is really Aramaic. No, seriously, it is an “Extra Initialization String” that is needed for the “Standard Modem over Bluetooth link” Advanced settings. (See Screen shot). I have the BES Unlimited plan, and these setting worked for me. Apparently if you run the BIS Plan, you must use AT+CGDCONT=1,”IP”,”isp.cingular” instead.
More to come.

Tethering is half the battle. Flushing the cache regularly to keep it running is another. Here is a trick to keeping TCP/IP stack clear and the Blackberry session open at all times.
At the C: prompt type:
NETSH INT IP RESET RESETLOG.TXT
Then reset the Connection Manager.
Who is using my name? and my blackberry???
Thanks! Just had to use this.
