This is how it is supposed to work.  IPV4V6 can also get you an IPV6
only session in case your APN is set up without IPv4.  There's a table
showing all the combinations here:

So IPV4V6 should always work and will give the optimal result.

The only problem is that it was introduced very late, in release 8 I
believe.  So there is a slight possibiliy that is unsupported in a 3G or
2G network.  Then you'll have to fall back to IP or IPV6 on the client
side.
