title: Sqlite disk I/O error on iphone 5
body: <p>i got an app uses SQLite intensively,
  it works perfect in the simulator, and also on iphone 4/4s</p>
  
  <p>when i install in on iphone 5 and greater, i got this error:</p>
  
  <pre><code>Unknown error finalizing or resetting statement (10: disk I/O error)
  </code></pre>
  
  <p>why is that happening only on iphone 5? there is 12 GB space free on the device.
  thanks!</p>
