I just bought a BT MP3/FM radio headset -- the 650 can pair with it, with the headset linking with the 650's correct "identity".

My problem is that the 650 will not preserve the headset's membership in the "Trusted Device" category.

The 650 & headset perform all the apropriate "Trusted Device" pairing tasks -- but upon completing that sequence, the headset is not in the "Trusted Device" listing.

P1 tech support told me I'm SOL because this headset is not on the Treo's compatible list.

I'm wondering if there's some way to manually force onto that "Trusted Device" list -- (and accept whatever incompatibility limitations that may exist) ??
