I don't have specific ideas, but have you tried troubleshooting by sniffing the HTTP/DAV traffic generated by the request? I generally use the 'tcpflow' command for this (not built-in, but you can install it with macports). This is obviously easier to do with the iPhone simulator than the actual device. This has been a huge help to me in debugging a lot of weird HTTP-related issues. I also recommend tcpflow -- just make sure you add "-c" to the command line so the output goes to console. In a pinch, "tcpdump -s 0 -A" will work just about as well for watching HTTP traffic. "-s 0" tells tcpdump to show you all packet data and "-A" prints the packet data in ASCII.
