How to skip the itunes sync process when debugging your mobile air app
Use Xcode to sync your app with your iOS device. Connect the device and start Xcode 4.x. Go to Window -> Organizer On the left side, you see the properties of your connected device, amongst them select "Applications". In the bottom of the right pane click Add. Choose your IPA, it gets added to the device automatically. Older versions of your app are automatically overwritten. This is way faster than syncing with Itunes and you get warned in case your provisioning profile is expired etc. - better than Itunes just telling you that installation failed without any further information.
