Experiences with mobile devices ?

I am using a Samsung I600 and when using it on WiFi with IPv6, it works like a charm (or rather it works as usual with IPv4 as well -- quite slow).

I have more problem with plain UMTS/GPRS as my mobile operator gives me a global IPv4 address, so, let's 6to4 start... and my mobile operator does not have any 6to4 relay in their network so it seems (traceroute to the anycast 6to4 relay) that all my 6to4 packets go from Brussels/Belgium to Amsterdam in the best case or to Switzerland in the worst case. Not optimum when you are in California and you want to reach a Californian IPv6 web server

In short, I would not blame the stack (except to prefer 6to4 to IPv4)
