title: iOS7 distributed App installation via iTunes fails without error
body: <p>After I my App as usually I tried to install it via iTunes.<br>
  It has successfully synced to the iPhone, but the Icon is grayed out and it seems like the installation has not finished</p>
  
  <p>Where you normally find the App-Name "Installation ..." has appeared.</p>
  
  <p>Can't find any log or error message</p>
  
  <p>(can't push the App with the development machine because of Apple's new security feature => "do you trust this computer" which just won't disappear)</p>
