  <pre><code> Troubleshooting wireless app distribution
   If wireless app distribution fails with an “unable to download” message, 
   check the following:
  
   -Make sure the app is signed correctly. Test it by installing it on a device 
   using iPhone Configuration Utility.
  
   -Make sure the URL to the .ipa file (in the manifest file) is correct and 
   the file is accessible to web users.
  
    -Make sure that the link to the manifest file is correct and 
     that the manifest file is accessible to web users.
