how to store iphone app's data even if it is uninstalled
<p>I have an app that has some consumable items, after they are used, user can do in-app purchase to get more.</p>

<p>How can avoid the user to unistall the app and reinstall so he doesn't have to pay?</p>

<p>Can i save some data that is going to remian regardless of if he unistalls it?</p>

<p>Should i have the app store in a database the udid of each device that it is installed in and when launched check that?</p>

<p>Thanks!</p>
