The folks over on HowardForums are reporting that AT&T will finally release the Windows Mobile 6 update for Samsung Blackjack users on September 17th. I hope this is true… While a beta was unofficially released on the web a few months ago, the lack of any Internet Connection Sharing was a big issue for me.
Internet sharing as in using the blackjack as a modem and connecting to it via USB has been working for awhile now. Is that what you meant? I know the bluetooth is so far unable to do the same.
Try this.
or just google "tether blackjack" for some walkthroughs.
