Long story short, I've discovered that when an iPhone with IOS 4.x is connected to a WiFi network that's got an IPv6 router serving a globally reachable prefix, it will, in fact, use it!
Here's proof: The Dancing Kame on an iPhone.
This page has logic on it to detect whether or not you are fetching it with IPv6 or not, and though you can't see the animation in the screenshot above, the text surrounding it is different than what you get over IPv4.
So, Apple.... what's stopping you from at least optionally supporting 6to4 over 3G?

Hey, I know I'm late to the party, but I have been very interested in IPv6 on the iPhone since I accidentally stumbled upon the IPv6 support in iOS 4.0. To answer your question, you can't run 6to4 on the 3G interface because you don't have a public IPv4 address. Learn more with the first dedicated iPhone IPv6 diagnostic app, IPv6 Toolkit. Oh, and Happy IPv6 Day!
