bluez 4.x documentation anywhere?

[Donatas G.]

Hi, is there any easy documentation for bluez 4.x that is used in Intrepid?

I used my phone as a remote previously in 7.10 and 8.04 versions, and it
does not work anymore.

I also had a bluetooth access point configured in 8.04, and it does not
work anymore...

All the documentation I could find by googling seems to be very much
outdated...
