BlackBerry 10 developers can now download the release version of the various SDKs.

There are three primary SDKs: native C/C++, Cascades which includes a C++ app and user interface framework, and WebWorks for HTML5 and JavaScript.

If that is not enough, there is also an Adobe AIR SDK, and a Java SDK which is compatible with the Android Runtime.

RIM has made a huge effort to attract developers to its new platform, though how it will fare versus iOS, Android, and a somewhat reinvigorated Windows Phone is open to speculation.
