title: Lite/Pro version vs In-app-billing upgrade option
body: <p>I have free version with limited functionalities&amp;ads and paid ver. with full features with no ads.</p>
  
  <p>I'm wondering, Should I make different ver. of app paid/free and upload it to market or
  Lite version and <strong>IN-APP-PURCHASE</strong> to upgrade to pro version?</p>
  
  <p>What should be the best choice in this case?
  if you can give insights of pros and cons of IAP and pro/lite method would be great.</p>
  
  <p>1Q:
  if user installs free ver.  > makes in-app-purchase > uninstall</p>
  
  <p>If he downloads it again then will he clicks in-app-purchase. Will Market ask him for money again (since he already paid?</p>
