This week, the BlackBerry Developer Conference was held. During the conference some interesting announcements on BlackBerry App World were made:

In-App Purchasing

Apple was the first store supporting In-App Purchasing, allowing developers to monetize both free and paid applications in various new ways. See more in our latest report. Good news for BlackBerry developers, App World will also start supporting In-App Purchasing in 2010. It is not yet clear if this will be available for both free and paid applications.

Carrier billing

Right now, consumers that purchase an application in App World, pay using PayPal. In 2010, carrier billing will also be supported. This will make it a lot easier to purchase an application, where the amount will end up on the user’s monthly phone bill. Carriers and countries that will have carrier billing are yet to be announced.

Themes and Widgets

Like previously announced, more content is coming to App World. Themes will now also be available in the store. A new type of content, Widgets, will also be supported. For the user, there will be no notable difference between the current applications and new added widgets in App World. Both Themes and Widgets are today not yet available in the store, but are coming soon.
