Bonjour networking now works. E.g. if you’re using Mac OS X’s “Web Sharing” feature to serve a web site using Apache from your Mac, you can now access that server from your iPhone over Wi-Fi using your-machine-name.local, rather than having to use the IP address. This was a curious omission from iPhone 1.0 — as James Duncan Davidson wrote back in early July, after years of using Bonjour (née Rendezvous), “it just seems weird to use IP addresses again.” (Thanks to Scott P. Richert.)
