Mauricio did you have any luck with your iMac and Harrier EVDO connection via bluetooth?

On panther I didn't get anywhere fast. But now with Tiger, a device discovery and service search lets you configure the bluetooth serial port, you can change it's properties to be a modem, and install it as a network port under os x. However when you configure a connection, put in the correct Telecom details etc, I choose Sprint PCS Vision as the modem... on the harrier I start the wmodem app and choose bluetooth...then attempt a connection, you can see the bluetooth connection initiate, and in bluetooth manager on the harrier see the powerbook serial port as an incoming connection, after a while it timesout and says error communicating with modem.
I have tried several different modem scripts from Verizon etc.. haven't got anywere...yet..
