OK, so we missed the original announcement of Theme Studio 3.0 a few weeks ago, but not to worry because it's been tweaked again (though still calling itself '3.0'). The new release of Theme Studio has bug fixes for installing to 3rd Edition smartphones, plus support for morphing themes and animated highlights. Here's the download page.

Don't get your hopes up too high though, it's still Java-based, interminably slow, with a strange interface and, on my PC, very buggy. Nokia, you can do better than this - please rewrite it in C++!
