As usual, with this new version, I have released the package for Nokia 770. Download it here. Don't forget to install libgnomeprintui too.
Unfortunately, I can not see a solution to show the application icon in Maemo task switcher. So please don't minimize Gnumeric window. If you do it you will have to kill Gnumeric explicitly using X Terminal or Load Applet.
This Gnumeric release "include numerous function fixes, fixes for a number of crashes and improved compatibility with Excel's functions, in particular for string functions." See the release notes.
