Since I upgraded my Blackjack II to Windows Mobile 6.1 I haven’t traveled anywhere where I needed Internet Connection Sharing to work. Getting ready for a trip this week I decided to test ICS before I got to the airport. I just assumed it would work but it wasn’t the case for me.
First off props to Steve Harman for already posting how to get into the phone and unlock the connections on the phone. Like Steve I figured the settings were not correct (I’ve gone down this road before with AT&T). Here’s how to fix the Blackjack II with Windows Mobile 6.1 to tether to your computer using Internet Connection Sharing (ICS) that is built into the 6.1 upgrade.
Step 1:
Follow Steve’s outline on how to unlock the GPRS connections via the registry.
You’ll need to download a utility. Here is the link for posterity sakes:

Step 2:
Once the settings are unlocked try to connect and see if you can. I was unable to. I kept getting:
The remote party has ended this connection.
I went back into the settings and added the following username and password to the AT&T ISP setting and then it connected. Success!
Username: WAP@CINGULARGPRS.COM
Password: CINGULAR1
When connecting to wap.cingular as the access point, I’ve always had to enter the username and password to get things to work. Maybe some don’t, I’m not sure what the rules are, maybe it is location based who knows. Anyway, I hope this helps. Cheers.
UPDATE 10/31/2008
When I was in Los Angeles, CA I had to change these settings. The only thing I got to work was applying the same settings in step 2 to the AT&T MediaNet connection.
