Will compiling with SDK4 to get the app switching still run on OS3?

    Since simply linking against SDK4 will give you the app switching code, does anyone know if the app will still run on OS3 if you don't change anything else?

    Thanks, Dan

    Depends what your project's minimum OS deployment target is set to.

    Yes, just set your Base SDK to 4.0 (rule of thumb: always try and build using the latest SDK for the platform) and the deployment target to the minimum supported version.
