title: Getting "A valid signing identity matching this profile could not be found in your keychain" warning
body: <p>I hope to test my app on iPod Touch</p>
  
  <p>I created development provisioning profile.</p>
  
  <p>I dragged downloaded .mobileprovision file to Organizer</p>
  
  <p>There is a yellow triangle warned that
  "A valid signing identity matching this profile could not be found in your keychain"</p>
  
  <p>The others distribution provisioning profiles have no any problem.</p>
  
  <p>I checked my connected iPod Touch. Organizer also said that:</p>
