I just got a Nokia 6680. I paired it with my Mac (10.4.3), and sent files via bt with no problem. I then opened iSync and added the device. I got up a message that iSync could see it, but not connect to it (no security message, just couldn't connect). I then deleted the pairing on both phone and PB, restarted both and started again from bt prefs / add device. At no time does my Mac attempt to install iSync agent, which I understand I have to have on my Symbian phone. And the only choice I'm given during configuration is to allow the phone to let my computer access Internet, not to sync contacts etc. I've searched and found good instructions on another site as to how to make sure my phone's prefs will allow programs to be installed, so I know the phone is good to go. Anyone else have this phone, this problem, and manage to solve it?
