I created an iOS app and want to distribute it Over-The-Air. I followed this guide:
http://help.apple.com/iosdeployment-apps/mac/1.1/?lang=en-us#app43ad77ea
There are a plenty of reasons to cause this message.
The best way to diagnose it is to connect a device to Mac and look Console for the device in Organizer.
In my case, for example, it was:
verify_bundle_metadata: This app was not build to support this device family
