HTC TyTN / 8525 / JasJam (Hermes)

I have had the phone for over 2 weeks, it's wonderful. 2 little things, though. The first is VERY minor. My old Nokia 6820 had a feature called "profiles", and you could set a timer to have the ringer go from vibrate/silent to ringing again. Can the 8525 do that, somehow? The other thing: at random times (usually when futzing with the internet), if I have the Bluetooth on and the phone rings, and I push the talk button, it often answers on the regular phone speaker, not the Bluetooth. Does anyone know what the story is with that? Thanks...
