Hehe...
I like the cut of your jib sir

yeah I remem. ...the 2008 hacker is pretty rough around the edges in spots.
hm...well concerning java..check out gronmayers page and the Jalimo repo.
http://www.gronmayer.com/it/index.ph...&system=maemo4
and
https://evolvis.org/plugins/mediawik...dex.php/Jalimo
and of course the subsection on maemo.
I believe it still is functioning properly
I don't know if it will work on os2007(or 8 for that matter) hacker edition.

Personally I think that the smoothest methods of devel for the older devices would be c++ or pygtk.
As far as the n800 and n810 go you will find them a lot smoother an experience with much more to offer and less troublesome to boot...(not that I'm knocking the 770...it does what it was built for admirably...and then some...it's just that the n8x0's are different beasts in compare.)
