i've got slightly the same issue, I've used my BT headset with tytn II, Touch, and ominia and all have worked fine, used it with polaris and it doesn't like it if you move the phone about - which sucks if you're just walking. I've flashed my polaris with 3 different rom's still the same issue, i believe its an 'imbedded' issue rather than a winmob issue. Thankfully the OEM headset you get with the phone is good enough to use. *edit* Have found that the issue is slightly better handled if you are using Mortplayer rather than the inbuilt mediaplayer - still aint great tho
