The President Theme is a free theme available in App World, compatible with all BlackBerry devices. On the 81XX, 83XX, 87XX and 88XX, this theme lacks a hidden dock, but you still get the basics.
This theme is very decent considering it’s free. It comes with the standard BlackBerry icons, and allows you to upload a custom wallpaper picture that gets framed within the theme. I think BlackBerry themes in general are really coming into themselves with more customization. If there was a paid version of this theme, it should include the ability to add stickers and writing to your picture, which is really popular in Asia.
