title: OData & Concurrency Token
body: <p>I'm building an application that needs to be able to store data offline and sync it to an OData server. While reviewing the videos, one of the presenters mentioned a <code>Concurrency Token</code> - can this token be used to help in the sync process? If so, how do I use it and what do I need to watch out for?</p>
  
  <p>For further info, my target platform is Android, so I'm unable to use the Microsoft Sync Framework.</p>
