title: Installing TestFlight on iOS 7
body: <p>After upgrading my iPhone 5 to iOS 7 beta, it seems I have to re-connect it to Testflight.
  Unfortunately, I can't install the provisioning profile:</p>
  
  <p>After selecting 'Reconnect Device', 'Install Profile', 'Install Now', the alert is 'Profile Installation Failed. You iPhone is not activated'</p>
  
  <p>I tried to remove the previous profiles, clear Safari cache and reboot, but no success...</p>
