Mobile Application Development with Ads

I am looking to develop an application that will work on Nokia, Blackberry, Android (Tabs + phones) iOS (iPad and iPhone) and Windows Mobile The application will support push notifications as well as should have Ads inside it, because the app would be free so I will make money through Ads only. It should have social plugins to share the content on Facebook and Twitter. App will be server driven it will show data from the server probably through xml. get back to me with your app portfolio. my skype id is bhagyavendra1.
