title: in-app purchase queryInventoryAsync doesnt return item which is already purchased
body: <p>I am using test Product Id  <code>(PRODUCT_ID = "1023608")</code> to implement Nokia In-App purchase.</p>
  
  <p>I can successfully purchase an Item using following code snippet.</p>
  
  <pre><code>mHelper.launchPurchaseFlow(this, PRODUCT_ID, RC_REQUEST, this, "");
  </code></pre>
  
  <p>I am getting succes response in <code>onIabPurchaseFinished</code>.</p>
  
  <p>When I try to query recent purchases using <code>mHelper.queryInventoryAsync(this);</code> I am getting <code>Owned items response: 0</code>.</p>
  
  <p>I was just wondering It should return me the product Id of purchased item.</p>
  
  <p>Can anybody please help me If I am missing anything ?</p>
  
  <p>Thanks :-)</p>
