Can you explain a little better. I think I understand what you are trying to do.

First, you will need to create a server side page that will display the data you want to store on the iPhone in NSUserDefaults. I would recommend having the page display the data output in json format, then use a JSON Parser library like SBJSON to parse the data into an NSArray then you store this information in NSUserDefaults. To get this data you can use an NSURLConnection.

To send data to the server it's much of the same thing you will need to use NSURLConnection to send the data back to the server either via POST or GET methods.
