title: What is XMPP, and how can I use it within an iOS chat application?
body: <p>I want to create a chat client application for iPhone. I've read that the XMPP framework is one of the best to use for this. However, I haven't found much material out there on this, only the XMPPFramework on Google Code and details about it on a wiki.</p>
  
  <p>Can anyone explain what XMPP is and how we can use it within our chat application? Are there any tutorials or code snippets out there that demonstrate its use?</p>
