I have been trying for the last 2 days for many hours to set up tethering between my 8800 (T-Mobile) and my Dell Precision M6300 running XP (SP3). I cannot get the modem driver to function. I have updated to the latest BB modem drivers and Desktop Manager (v4.7 w/ Device Manager v4.3.1.15 and RIM USB Driver 4.1.04 and RIM USB Serial Driver 2.1.04)

When I set up the Modem I used the recommended special configuration code for T-Mobile +cgdcon=1,"IP","wap.voicestream.com"

However when I Query the Modem I get no connection.

Anyone have any thoughts? Im about ready to give up...
