I am able to use my phone seamlessly with iSync but having trouble setting it up to be used as a modem.
As you could probably tell form the picture I posted. The drop down options are all grayed out and I can't click on them. And all the input are also frozen.
But the two check boxes in the bottom work fine and the buttons work just fine as well.
I was able to use the bluetooth modem feature with my Nokia E61 a year or two back. but having problems now.
I am wondering if there is something to do with the modem scripts. or if there is a way to reset the modem scripts.
