I just stumbled upon a great new theme on BlackBerryforums for the BlackBerry 8800. The theme is based on the movie the 300 and has quite an interesting feel about it. I am surprised that advertisers have not started hyping movies with free themes but this is a pure fan creation by BlackBerryFreaks.com. There is both a OTA and desktop download option.
