The platform is iPhone OS 2.2.1, if that helps. The Apple documentation for CFReadStreamCopyProperty() doesn't say anything about why it might return NULL. Furthermore, if I comment out the code trying to get the response, the rest of the code works and I get the data from the URL. What am I doing wrong?

Sounds like you're calling CFReadStreamCopyProperty too early - You can only copy the kCFStreamPropertyHTTPResponseHeader once it has actually received the bytes comprising the header. (calling CFReadStreamRead as I'm guessing you do later just blocks until there is data available)
