Maemo, the development platform for Nokia’s Internet Tablets is one of the organizations participating in Google Summer of Code 2007. SoC is a program that offers student developers stipends to write code for various open source projects.
I’m one of the mentors for Maemo projects. Students can apply for the program until March 26th. If you want to work on Maemo (and especially positioning-related) applications, add your idea to the wiki ASAP!
