Re: [RRG] 2 billion IP cellphones in 2103 & mass adoption of IPv6 by currentIPv4 users

There's a lot of NATting going on in this space, and an active
desire on the part of management to provide the minimum of 'true' IP
connectivity which users will accept and pay for, due to fears of
service bypass, the desire to keep the user in a 'walled garden' of
metered services, oversubscription concerns, etc. The service terms
for many wireless services often explicitly forbid the use of P2P
technologies like BitTorrent, and in some cases ftp and other
protocols/services which are viewed as being undesirable due to
typically heavy usage patterns.
Note that the handset manufacturers are very responsive to carrier
requirements in terms of the capabilities that they design into the
handsets, even in markets where unlocked, individually-purchased
mobiles are the norm. AFAIK, none of even the most modern
smartphones support IPv6, or allow it to be enabled by the user
(correction welcome); which is rather ironic, given that, at
present, IPv6-based mobile networks would represent a garden with
especially high walls.
This is a handset manufacturer rather than a wireless provider but
they seem to have given IPv6 some thought.
About 8 minutes into this presentation they talk about one reason
why they are interested in IPv6.
About 11 minutes in there is a list of mobile devices that have
support for IPv6, this of course doesn't address the issue of whether
it's allowed to be enabled by the user on a given wireless provider's
network.

Also, I've yet to see a wireless access service which supports IPv6
even for general-purpose computers connected via wireless adaptors.
None of the mobile network operators with whom I've interacted
provide IPv6 connectivity at all, or have disclosed an intention to
do so in the near-to-medium-term future.
As to long-range plans, my subjective impression is that most of the
mobile operators to whom I've spoken are just now coming to grips
with the implications and requirements of operating production-
quality IPv4 networks, and IPv6, even though it would at first blush
seem quite attractive to them, is in many cases not even on their
radar. I'm sure this will change over time, but quite slowly, given
the industry characteristics noted above.
