Hello,

I'm currently working on an application that needs to check a web service for an updated version of a locally stored XML file. If there is an update the file must then be downloaded and saved to the iPhone. I'm not really sure what direction I need to head in.

Currently I know that I can use NSURLConnection delegate methods to establish a connection and receive a response but I'm not sure how to implement this with the web service to grab the file and replace the current one that is stored on the iPhone.

Any help would be greatly appreciated.
