title: Managing user session with devise on iPhone APP
body: <p>I have a Rails application for which I use devise to authenticate my users and this works great.  I now want to write an iPhone application (not just a WebUI but a proper APP) that accesses the same data and so requires the same authentication.  How should I go about doing this?</p>
  
  <p>I want to login using devise and keep the session open so that queries back and forth work as they do on my website.  I am very new to both rails and devise.</p>
