Thanks to the originator of the instructions and all the posters updating information. I just purchased an 8100 on Cing Orange, followed the instructions (modified with the "wap.cingular") and it works GREAT. I have BES UNL, so I hope it won't show up as a $1,000 bill!!

Have you gotten a bill yet since using the "wap.cingular" setting?

I was wondering though, I had previously done something like this on my Treo and when using "wap.cingular", the Username was then WAP@ rather than ISPDA@.

Below are instructions I found that are similar to what I used before my BB:

Connection Name: whatever you want i named mine wap.cingular
Modem: bluetooth dialup modem
Phone number: *99***1# (turn dialing rules off)
Username:
Password: CINGULAR1
**click advanced tab**
Baud rate: whatever i use 19200
uncheck wait for dial tone before dialing
Extra dial string: +CGDCONT=1,"IP","WAP.CINGULAR" (case sensitive and that is an O not a zero)

Again - thanks to everyone for all that I've gleaned on BBF!
