title: MonoTouch check amount data consumption
body: <p>I've made an MonoTouch app for the iPhone where the data is accessed by several web services. Because the clients have a subscription to a phonecompany, they have a max. amount of data to consume per month.</p>
  
  <p>Now my question, how can I check the amount of data that is consumed during the run of the app on the iPhone?</p>
