Please help a connection searching iPhone out and give it an IPv6 address. And while at it, a default router too. After being so nice, I am sure you've collected enough karma to warrant some cookie sniffing or even the occasional traffic modification.
In about 3 hours on a public hotspot I saw nearly 30 [that is thirty!] iOS 4 iPhones crying for router solicitations. Knowing the rules layed out in rfc3484, it should not be to hard to get the application/OS to prefer v6 over v4. This makes getting these pesky SSL'ed cookies so much easier without ARP poisoning.
