title: Coding a "trial run" into an iPhone App that connects to the AppStore
body: <p>I have created an application and I have purchased an account in AppStore.</p>
  
  <p>I wish to configure the app such that it will run for free twice and after that the user will have to purchase the full version. I want to implement the purchase of the full version inside the trial version (using in-app purchases).</p>
