Hey TeddyEdward, you are the man. This fixed my iPhone 4s, iPad 1 both for AirPrinting (perfectly; to an HP Officejet 8600 n911a) and for AirPlay to our Apple TV!!
This is probably the best techy thing that's happened in my sad and multimedia developer life for a while! Now I just have to figger out how to justify a 27" TBolt display..
