is it possible to run blackberry OS 10 in blackberry OS 6,7 and 7.1

Question

I am new to blackberry development; please let me know is it possible to run blackberry OS 10 apps on blackberry OS 6,7 and 7.1? Or vice versa?

Also i want know how to develop a flip board type application for blackberry OS 10, or OS 6 and 7.

Answer 1

BB OS 10 and BB OS 7,6,5 are not compatible. Thers is no such thing like binary code compatibility between BB 10 and BB RIM OS 7.x and older devices.

But there's a workaround. Use HTML5/WebWorks to implement an application and compile it for every platform. In this case this application will work on BB 10 and will work on legacy RIM OS devices (7.x, 6.0, 5.0).

update:

There are two WebWorks editions. One for BlackBerry OS, another for BB 10 OS.
