Not sure if that's what you looking for.... I think mighty ROM might not have included all those settings. I just tried to tether with BT just now and it works for me. I am using mighty ROM.
unfortunately my BT tethering experience is not as stable as usb or wifi. The phone BT DUN crashed about about 20 MB of data or about after 15 min of BT tethering everytime. So right now I tether with usb and wifi. Would be nice to have another stable tether option
I never really tether with the phone not connected to a power source. Figure the power drain is just too much. It definitely unlikely to last anywhere near the talk time (4 hrs?). how long can you tether with BT and phone on battery only?
