I'd like to see an app for an Artificial Horizon...just select the app
and place the device onto your panel via a large piece of velcro...

There hs been several threads on using an Iphone on the various
aviation groups. Do not attempt to use the little AH app you can
download on Itunes for flying. The Iphone does not have gyros. It
uses
accelerometers which will not help you in an airplane.
