Perhaps because of its extremely time-limited nature, there aren't many themes out there to celebrate the New Year.
However, we've managed to find a small number of appropriate themes for your S60 3rd Edition phone, and they're all free. There were actually more New Year themes out there, but the themes below were the only ones that were relatively readable, so they're the ones we're recommending.
Simply click on the name or image of the theme you want, and you'll be taken to its download page.
If you don't know how to install S60 3rd Edition themes, watch this video tutorial on the Nokia Duck blog.
