What is the cheapest way to publish app to itunes? I have flash cs5, but i do not have the money to buy unity pro right now, or unity ios. Is it possible to use the free unity to build then export to flash and publish?
No, Flash export uses Stage3D which is not supported for iOS.
Once Flash export is released, it will be a paid add-on as well.
Does Flash CS5 no longer do exporting to the iOS?
If so you need then an osX computer, xCode, and an Apple Dev Account to publish the Flash CS5 iOS export to the app store.
