title: Google+ SignIn Button with PhoneGap
body: <p>How can we use the JS Google+ Signin button with Phonegap?  Specifically for iOS?
  I have found <a href="http://lifehacker.com/302197/useful-command-line-tricks-for-mac-users" rel="noreferrer">this article</a> on doing oauth with phonegap and the childbrowser plugin however I'm not sure that approach will work with the Google+ signin button.  Any Ideas?</p>
