Since NSString's -initWithData:encoding: method returns nil if the data isn't valid for the given encoding, that's the first thing I'd check for. Check the response HTTP headers to make sure the server says you're supposed to be receiving UTF-8 encoded text. If so, try saving the received data straight to a file with NSData's -writeToFile:atomically: method and opening it in a text editor (such as TextWrangler) to verify that it really is UTF-8.
