  <p>I've tried it's on both <strong>Windows 7</strong> <strong>32bit</strong> &amp; <strong>64bit</strong>. 
  I'm using HTC Desire <strong>Android v2.3.3</strong>.</p>
  
  <p>When I try connecting the client to the server and try to write any text using <code>OutputStream</code>, i get the error: </p>
