Yes, the majority of handsets in the beta are N900s. It is the only place where power users who know what IPv6 is and IPv6 supported hardware converge.

Nearly all S60 phones support IPv6, but S60 users generally don't know or care about IPv6. And, people who know what IPv6 is do not want to use S60.

Android 2.3.4 has some new IPv6 code added that helps with IPv6, but we are still waiting on the OEMs to produce the required solution (including devices specific RIL) to make Android phones work with IPv6.

I am crossing my fingers that Meego will provide IPv6 support.
