My latest experience on converting Flex App to iOS, might be of use for beginners.
Debug version ipa generation is faster than rest, make sure you select Ad Hoc Distribution for testing the app on any device with Developer licence and Developer Provisioning Profile.
Make sure you use Mac for porting the application with Apple’s iPhone Configuration Utility, otherwise with windows use iTunes for porting the app into Device.
You cannot install IPA files to the device via Apple’s iPhone Configuration Utility on WIN, got error “Could not install application on device. Error kAMDReceiveMessageError”. Workaround is to install IPA with iTunes on Windows or iTunes/iPhone Configuration Utility on Mac OS (2810687) (source : http://kb2.adobe.com/cps/891/cpsid_89107.html)
