Cool: iPhone OS 4 does IPv6 (on an IPv6 enabled Wifi network)

Cool: Apparently iPhone OS 4 does IPv6 too, as I found this entry in my webserver log file: 

2620:0:da0:4003:6233:bbbb:fedb:aaaa - - [20/Aug/2010:18:00:01 +0200] "GET /set-ipv6resolving.js HTTP/1.1" 200 21 "http://www.appelboor.com/ipv6.html" "Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_0_2 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Version/4.0.5 Mobile/8A400 Safari/6531.22.7"

(IPv6 address changed a bit for privacy reasons).

The IPv6 address is from Louisiana State University, so it's not IPv6 over UMTS/GSM or something like that; it's probably an iPhone on a University Wifi network doing IPv6, visiting http://www.appelboor.com/ipv6.html to check his/her IPv6 connectivity.
