LTE does not have the dual attachment problem since there is the concept of having v4 and v6 in one attachment, but it does not change the fact that there are not enough IPv4 addresses to go around, especially from a strategic planning perspective (let's design this once for 5 to 10+ year life ...)
Actually, GTPv2 with v4v6 bearer works in GSM/UMTS as well, but one has to software upgrade all components to make sure it's supported. Unfortunately this is still a future roadmap item for a lot of vendors. This of course needs to be supported in the end user devices as well, but the LTE dongles when in 2G/3G will hopefully still support this. -- Mikael Abrahamsson email: swmike@swm.pp.se
