OSX accepts route advertisements on Ethernet interfaces, but by
default it's disabled on point to point interfaces.

On OSX Leopard and early patch releases of Snow Leopard, you 
could turn on the net.inet6.ip6.accept_rtadv, but you'd get
a kernel panic as soon as the first advertisement arrived. 
Which is probably why the setting defaulted to "off" :)

Apple fixed that in later versions of Snow Leopard (I think it
was .5 that had the magic patch), and since then you've been
able to run dual-stack point to point links if you turn on the
sysctl and if the device at the other end does the right kinds
of LCP negotiation (IP6CP needs to come up in PPP).

There's no reason to think iOS wouldn't behave the same way.
