Admob with version 4.0 only?
<p>I am looking at introducing admob to my application which is developed in version 2.1 so it can support all devices. However I think that I just read that admob will not work for any devices that are prior to 3.2 or 4(cant remember) and that the most recent admob SDK should be downloaded or it will not work.</p>

<p>Can you confirm my undertsanding and if so what should I do to make ti run on olderversions?
Thank you</p>
