Is there a way other then being Nokia to write an application for global hotkeys/hooks on Series 40 (6th edition)? The only way to add user code appears to be Java, and the Java sandbox does not seem to allow multitasking with other phone applications.
My specific goal is to 'fix' the issue with several Nokia feature phones that don't include dedicate volume keys, but do include a pair of extra application shortcut keys which are only used on the home screen - remap these keys to control the volume from any application, if possible.
