Look into ASIHTTPRequest. You're going to want to use the setDownloadProgressDelegate: method to hook it up to your progress indicator. Something like this:

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDownloadProgressDelegate:someProgressIndicator];
[request startSynchronous];
