How do we implement this? for example: I have a "Lite" app that allows user to unlock some "Pro" features using In App Payment.

So what do I need to do? Once the payment succeed, what should I do to keep the Unlocked features stay Unlocked the next time user launch the app?

Thanks

I have created a local database that stores what the user has purchased.

This is then loaded when the user loads the app.

What happens if user figures out where you store it and will modify the database to set purchased options without purchsing? I thought there was an API to query app World for list of purchaased features which you can then use to make decisions what to enable.disable?

Applications are sandboxed so that other apps would be unable to modify this data...

you must check what first item will unlock by user
