Using the instructions I was able to get to the second to the point where I have to enter the address of the bluetooth headphone. I too receive the message sbc-svn_20070608-1_armel.deb not found.
If I ignore that and gainroot then issue ./install sh I receive install not found.

Tried to follow your corrective procedure but nothing worked. Nothing listed in Application Manager to uninstall. Don't know where to go from here. Can't find armel.deb either.

Had the N800 2 days but I have a pair of Lubix bluetooth headphones and want to be able to use them.
