title: When to use an explicit app ID versus a wildcard ID?
body: <p>What are the exact advantages of creating explicit App ID and Wild card ID? I saw that if we are creating a bundle of apps, we can create a wildcard App ID, otherwise explicit ID is good etc. But I am a bit confused and want to know more details about the exact advantages of both types.</p>
  
  <p>If I have a free version first(1.0) and then want to submit priced version of same app with new features(2.0), what should be the right way?</p>
  
  <p>Thanks.</p>
