IIRC, it was a dirty hack back in the ITOS2007 days. No idea if
ITOS2008 improved that. Never owned a bluetooth headset, so no idea.

Bluetooth headsets in normal mono HSP mode work well on 2008 - you can
pair one, it will be detected as HSP and will be automatically
connected/reconnected.

But as far as I am aware of there is no A2DP (stereo) support in OS2008
yet - though the Linux-BlueZ support is quite well by now.
A2DP can have several sub-profiles defining the codec used to transport
the audio stream, one of them is the "sbc" and there is also a MP3
profile, i.e. you can directly stream MP3 data over A2DP to a headset
that supports it. Most stereo headset though only support sbc not MP3 -
and BlueZ A2DP currently only supports sbc.

Long story short: Linux-BlueZ can handle A2DP sbc but this is not yet
properly integrated into OS2008.

Thanks for the detailed information. We need A2DP in OS2008. A2DP sounds
much better than just mono. I hope it gets added soon!
