ran across this project from a group called DataDyne - with it you can create data entry forms on pda/java enabled phones. it's free and targeted for use in developing countries here
and it seems they are working with the nokia non-profit branch
it's a useful example of the sort of projects we're working on in class. if anyone else downloads and looks at the code, i'd be curious to know what aspects you think are optimal and which should be avoided/improved on.
