I was actually up to port some useful Linux-Apps to Qt/MeeGo in order to customize them for the upcoming N9 phone. There are several fantastic GPL-apps I would really love to see on my smartphone.
Since Nokia is not releasing the N9 in Germany, I will now have to port these apps to Windows phone.
For my N900 I could easily recompile the source for arm (most Linux apps are unter the Gnu Public License and the source is therefore available and can be modified) to get them running without much of efforts. How can I do that for WP7? How do I publish GPL-Apps for WP7, and, is it free?
I would like to use Qt on WP7. Where can I get a Qt installation for WP7?
