title: UIWebView "Unable to read document" error
body: <p>I am trying to open Word and Excel 2003 docs using loadRequest and I am getting this error
  (in simulator).
  Unable to Read Document.
  An error occurred while reading the document.</p>
  
  <p>According to this link, 
  <a href="http://developer.apple.com/library/ios/#qa/qa2008/qa1630.html" rel="nofollow">http://developer.apple.com/library/ios/#qa/qa2008/qa1630.html</a></p>
  
  <p>UIWebView should display doc and xls types.</p>
  
  <p>Any ideas? 
  Are there any other recommended xls, doc viewers out there?</p>
  
  <p>Thanks.</p>
