There's now a build of the latest Python for S60 (PyS60) which installs without errors on S60 5th Edition devices like the Nokia 5800. v1.9.3 introduced quite a few enhancements, chief among which was support for touchscreens. Though this build will be of interest mainly to developers, I suspect several professional applications for the 5800 written in Python won't be far behind now. (via Croozeus)
