NSURLDownload is not available for the iPhone OS. Use URLConnection instead.

From the iPhone reference library:

iPhone OS Note: The NSURLDownload class is not available in iPhone OS as downloading directly to the file system is discouraged. Use the NSURLConnection class instead. See “Using NSURLConnection” for more information.
