Hi,

If you don't have IPv6 from your ISP, then that is expected. That doesn't change
the fact that my patch does introduce a regression for those without IPv6, them
having to manually disable it (setting ipv6 to 0 selects "IP" by default). I'll have to
think the defaults through again, most likely changing PDP type "IP" to be the
default unless IPv6 is explicitely _enabled_.

Thanks for reporting!

Matti
