title: NSInvalidArgumentException error with Phonegap 2.1 and facebook plugin
body: <p>I've been following the facebook phonegap plugin install instructions here: <a href="https://github.com/davejohnson/phonegap-plugin-facebook-connect" rel="nofollow">https://github.com/davejohnson/phonegap-plugin-facebook-connect</a>.</p>
  
  <p>After taking my time and follow every step very closely, I was able to build the project successfully in the simulator in xcode. I am using phonegap 2.1, which I downloaded off of the phonegap site, NOT directly from github.</p>
  
  <p>The splash screen loads fine, but once the app goes to run this is the output from xcode:</p>
