There is preliminary OS2007HE support for the 770 in the trunk. I still need to play with package building on that platform, but you can run it yourself if you checkout the code, "build_script.sh os2007" and then copy the contents of "build-os2007" to your device.

Sorry, I'm not running OS2006 but if anyone is, hopefully its close enough.

The only issue I detected is a cosmetic issue with tabs. Every other tab is bogus and the tab labels are bad. This was one minor change in the glade file that is just off enough that my limited regex skills were not able to handle it (currently we transform the code to each supported platform). The "770" branch I used for experimenting has a glade file that does not have this issue since I made the changes by hand.
