Using iPhone 4 (v.4.3.3) Jailbroken.

Does anyone know if there is a hack which will allow me to trigger a change of orientation (portrait/landscape) using an Activator 'action' like 'status bar swipe down' or 'double-tap clock'?

I have a physical disability, including impaired hand movement, and rotating the phone to change orientation is tricky for me.

There are lots of orientation hacks on Cydia so I'd guess this kind of hack is possible, I'm just not sure if anyone has implemented what I'm after.

Many thanks.
