Getting Blackberry 8700c to work as a modem

During the install of my new Thinkpad, I had to get my Blackberry 8700c (Cingular) to work as a modem again. I followed the directions available on BlackberryForums and on Cingular's website, but was unable to get it to work as they specified: [HOWTO: Use BlackBerry As Modem] [Cingular: Configuring a modem in Microsoft Windows for tethering a RIM BlackBerry] [Cingular: Creating a Dial-Up Networking Connection for Windows XP via USB Cable]

The change I made was to set the extra initialization string to:

+cgdcont=1,"IP","WAP.CINGULAR"

... instead of the one they specified. And now, it works. :)
