I would LOVE to know how you did it! I've spent several hours trying to get tethering from my iPhone 4 to work. I have tethering activated on my non-jailbroken iPhone 4. I can connect to it from my MacBook Pro and Alienware without issue via both bluetooth and USB. When I try either in the Edge, it's a no go.
When I go to Bluetooth settings from the wireless setup screen, and Select Internet Data Connection, I see a flash of a screen that show DUN and PAN options and other stuff I can't read quikcly enough. I get stuck on a
/Phone/Internet Settings setup screen that is black with no input options. The phone pairs fine with the Edge for all other stuff, but this just isn't working. VERY frustrating and there doesn't seem to be any worthwhile documentation available on the subject.
If you can provide any enlightenment, it would be GREATLY appreacited! :-)
