I cannot be of much more help (I remember that getting everything 
working was a pain) but the wiki says not to use ipv4v6 unless you're 
absolutely sure the carrier provides both.

This is my configuration (I did it through luci)


config interface 'wwan'
         option proto 'qmi'
         option device '/dev/cdc-wdm0'
         option apn 'movistar.es'
         option auth 'pap'
         option pdptype 'ipv4'
         option username 'MOVISTAR'
         option password 'MOVISTAR'
         option metric '2'

(dhcp is the default, metric is because at home I used a lan port to 
simulate the wan).

Regarding your question about wwan0 being POINTOPOINT and dhcp, I can 
confirm that it's POINTOPOINT here too, but it gets an address (in luci 
I see both a wwan interface with no address and a virtual wwan_4 with an 
ipv4 public address, both using the wwan0 device).
