1. Prepare Pure and Bell specific `Application` classes and add them to `app` target: - `products/BellHybrid/apps/Application.cpp` - `products/PurePhone/apps/Application.cpp` 2. Update `CMakeLists.txt` files. 3. Move `ApplicationBell` implementation to Bell-specific `Application` class and remove `ApplicationBell` files. 4. Change Bell apps parent classes from `ApplicationBell` to Bell-specific `Application` class. 5. Rename `Application` to `ApplicationCommon` in the rest of the files.
