title: Unibill, testing iOS In App Purchases & Unity
body: <p>Big headache! I cannot get IAP to work on my iPad device.</p>
  
  <ol>
  <li>I have created a developer account on iTunes.</li>
  <li>I created some app information, SKU etc., without uploading a binary.</li>
  <li>I have set up Unibill to use the bundle identifiers and Ids as shown in the iTunes dashboard.</li>
  <li>I logged out of existing users on the iPad.</li>
  <li>I created a test user with a new email.</li>
  <li>I fooled around with Xcode settings, trying a million different settings, but mainly following the documentation best I could: specifically, linking the Storekit library.</li>
  </ol>
  
  <p>Unibill initialization keeps returning a 'CRITICAL_ERROR'. Maybe it's a Unibill problem, but what could I have forgotten?</p>
  
  <p>Does testing In-App Purchases require a special contract type?</p>
