title: Naming convention for CFBundleSignature and CFBundleIdentifier
body: <p>I am wondering how do I know what name I should give for my CFBundleSignature and CFBundleIdentifier.  I believe these are supposed to be unique identifier so do I have to somehow get these names from apple?  Say my app is called javaapp and comes from the website javaapp.  Should my CFBundleIdentifier be com.javaapp.javaapp?  What 4 letters should I use for my CFBundleSignature?  </p>
