title: Install APK in Blackberry 10: Unable to install this app
body: <p>I've build a sample android app with phonegap 2.9.0 tried to install the apk in blackberry Q10 (10.2.1.1925)
  But I get the following message:  Unable to install this app</p>
  
  <p>I've also tried running a plain android hello world app and still got the same message.
  Funny thing is that other apps seem to install correctly.</p>
  
  <p>I read somewhere that you have first to execute an android app and the install your apk.
  I tried that it didn't work either..</p>
