This should please all you BlackBerry toting OS X users out there. Alex King has been on a mission for some software that would allow him to tether his Mac to his BlackBerry, enabling him to take advantage of the BlackBerry as a modem. He went so far as to collect a bounty of $700 for the first person to get this working.
Daniel Pasco got it working, and he has also gotten himself the bounty. Alex has tested it, but Daniel is still working out some of the kinks. It has been tested on the 8700g and the 8703e.
And remember, if you're a BlackBerry junkie you should be reading BBHub where BlackBerry is king!
