iPHONE - can I have a limited functionality application?
<p>I am about to create a light version of an app of mine. </p>

<p>My idea is to have the same application and limit its functionality. For example: suppose my application allows 4 modes of operation. The lite version would contain the first mode unlocked and then, if the user selects one of the other modes, show a message saying these other modes are just available in the full version. Then a BUY NOW button would be provided.</p>

<p>Is this possible to do? I mean, is it against Apple rules?</p>
