I'm not sure if the 3G phones uses IPv6, I think we still have only IPv4 in
cellulars, you know they want to have something "new" for 4G phones

But it's really just a question about a minor firmware upgrade to make a
cellular to use IPv6 instead of IPv4, if it don't already support it/both.

Yeah, from the protocol point of view it's the same, seen that those Series60
phones with which you can use tcp/ip over bluetooth you need a pppd on the
computer out over the dhcpd.

There isn't any major differences between IPv4 and IPv6, except the larger
amount of possible ip-numbers with IPv6.


Anyhow as soon as we managed to switch over to IPv6, we will not have problems
with ip-numbers not being enough, think everyone on earth could have far over
100 devices each that had their own ip-number (correct me if I remember it wrong).


One thing I got to think of, you remember all those dial-up modem pools for
internet that people had to use back in the old days, I think many of those
ip-numbers are freed today, both for broadband and for 3G/GPRS based internet
connections.
