Samsung just released a set of videos from the Bada Launch Ceremony that was held on December 8 in London. Bada is a software layer that Samsung has added on top of its existing proprietary mobile phone operating system. This will allow developers to create applications for Samsung’s phones. Right now, developers can already get their applications on Samsung phones using Java, but the goal of Bada is to make this easier and give developers access to more phone functionality in order to create more compelling apps for consumers.

The first Bada devices will enter the market in the first half of 2010. Developers can start to create Bada applications with the SDK Samsung published.

The videos show some interesting announcements for Bada and the Samsung Application Store. First, the Bada platform enables developers to use In-App Purchasing for their Bada applications:

The details on how this will work in relation to the Application Store are yet to be announced. Samsung also said that Bada applications will be available in the Samsung Application Store, which is currently available in the UK, France and Italy, and supports Windows Mobile applications. In the beginning of next year, the number of supported countries will grow to 50, Samsung announced.

To purchase Bada applications from the Samsung Application Store, consumers will be able to use a credit card or operator billing. In the presentation Samsung highlighted that a user of the store will not be required to register before buying an application:
