Got an advice to add 'devmatch_blocklist="if_cdce"' to rc.conf and that 
took me a step further, if_ipheth correctly idenfies the phone and ue0 
is added.

Now the phone asks if the computer is trusted, I confirm and start 
usbmuxd following the if_ipheth manpage (it used to start automagically 
in 14.0) and a service netif restart ue0

After this dhclient runs but ue0 seems down and does not receive an ip 
address/defaultrouter etc.
