title: Finding App Id under .ipa or .app
body: <p>I'm building an application that search and recognizes any iPhone apps that user has in his/her computer. I would like to know a way to "extract" the id of the application from the .ipa file.</p>
  
  <p>I was trying to do the recognition using only the App File Name, but I discovered that the File Name is not the name of the app in Apple Store.
  Live Poker 6K Free by Zynga != Live Poker 3.7.ipa</p>
  
  <p>The id i'm talking about is the app id, like in,
  <a href="http://itunes.apple.com/app/live-poker-6k-free-by-zynga/id354901953?mt=8" rel="noreferrer">http://itunes.apple.com/app/live-poker-6k-free-by-zynga/id354901953?mt=8</a>
  the id is 354901953.</p>
  
  <p>Does any body has a clue how can I manage to find this information?</p>
