There is 151 themes in 2 categories (free and paid) and 8 different subcategories (Abstact, Nature, Technology, Holiday, People, Transportation, Movies and TV, and Sports) available so far. Some are free, some are premium, but nonetheless they are available through the App World. If you like themes you might want to see what’s available, but there’s more.
Just so you know, there are only 7 free themes available out of the 151. We have over 300 and counting themes in the BlackBerry Sync Store, many are free. There are also $.99 themes in the BlackBerry Sync Store, which I didn’t see available in the BlackBerry App World. Currently BlackBerry App World requires a PayPal account, while you can bill to your credit card or gift certificate through the BlackBerry Sync Store. There were some really nice themes available in App World, and some were free for a short time only.
