BerryReview recently posted about Michael Smalls, a BlackBerry theme designer who has released over a hundred BlackBerry 8100, 8300, and 8800 themes for free. The design of the website leaves quite a lot to be desired, but the themes themselves are well done and there is a lot of variety. If none of the themes are entirely to your liking, you can even contact Smalls to have one personally designed for a $3-$10 fee depending on complexity. Fair warning: the site absolutely requires Internet Explorer on a PC to download the themes. There’s always Gemblock, who also does a lot of free themes.
