The process isn't easy but I have started taking Maemo5 Themes and redo them to make them work on OS2008 for everyone holding on to there N800s and N810s. I am glad to do the work I just ask any theme designers that want there theme back ported to OS2008 please send me there Source png or psd. It takes me about a week to tear it apart and rebuild it for OS2008 but with all the new people getting into theme design this would be a great way to get new themes on the old devices.
