I recently had this issue and found the answer on the MobileIron support portal. MobileIron requires the following attributes to be set in Info.plist: CFBundleName, CFBundleIdentifier, CFBundleDisplayName, CFBundleExecutable, CFBundleVersion, CFBundleShortVersionString
In my case the ipa I was given was missing CFBundleDisplayName, which is apparently not set by recent versions of the AIR SDK.
