Do you have Xcode and the ability to build onto a device? (i.e. a iOS developer account)
Input support should be possible if you pass through the device accelerometer and touch information to #accelerate and #touch receives respectively in the patch.
Off the top of my head accelerometer data is packed in to a "x y z" list, and touch is "touchIndex x y state" or something similar. Where state is up/down/move. If there's a certain patch that utilises touch it shouldn't be too difficult to reverse engineer the correct formatting.
