Hi can any body tell me how to add the feature of In App purchase premium version of application. Infect i want to sale my application free but some of the features will not be available in free app. To unlock all the features user will have to purchase a premium version of app. So can anybody guide me how to this?

A simple Google search would have been pretty successful on this.
I have already implemented InApp purchase facility by considering both :
this tutorial
and dedicated Apple documentation
Hope this helps

You can either create a limited functionality free version and a full paid version = 2 applications in the app store.
Alternatively you can create a free app with options for user to purchase / unlock certain areas of functionality. A simple google search turns up: http://troybrant.net/blog/2010/01/in-app-purchases-a-full-walkthrough/
