title: In App purchase and paypal
body: <p>I have to create an application in which the user are of two types : basic and premium.
  Now the problem in that a user can change its type using website and from iPhone application as well.</p>
  
  <blockquote>
    <p>So tell me is there any issue if we allow user to change the user type
    either from application or from website i.e. using Paypal.</p>
  </blockquote>
  
  <p>As per the guidelines of apple we can not unlock any feature in the application using any other mode except InApp purchase.</p>
  
  <p>So please advice.</p>
