title: How to detect "IAP crackers"?
body: <p>I found out that many users use so-called "IAP crackers" instead of purchasing the items in in-app purchase (IAP). I also learned that Zynga Poker and Pokerist already detect IAP crackers and prevent the fake IAP. I would like to detect which phone is using IAP cracker. For Cydia hacking tool, I could find it with Application path.</p>
  
  <p>But for I don't believe iAP crackers fall into specific applications. I think I can check that by calling "Url Scheme" but I don't know the name. Is there anybody who knows how?</p>
