I am new into the apple development and am developing an application which would present the user with a magazine which is available through in-app purchase from the user. When a new magazine is available, what changes should I make so that the user is able to view the newly available magazine on the iPad. More precisely, do I need to add an in-app content with a new productID on the iTunes account? Is there any way so that whenever a new content is available on the server, it gets automatically updated on the iTunes account as well? Also, if I add a new in-app content on the iTunes account, what about the apple approval process? Would the app itself has to go through the approval process or is it just the in-app content only that has to go through the approval process?
