title: mobile web app - keyboard not appearing
body: <p>I have a mobile web application, working well on simulator 5.1/6.0, xcode 4.5 for iphone.
  But when I test on a real device (3gs, ios 5.1), I get a strange behavior: anywhere I place an input field html element, where I need the user to fill in something, I tap the field, it gains focus (I see the cursor), but the touch-keyboard does not come up and I can't type anything. If I try it on the sim, all is fine, the kb comes up.</p>
  
  <p>I am not sure how to diagnose this... tried googling for some answers, haven't found any :(</p>
  
  <p>any ideas?</p>
  
  <p>thanks...</p>
