Ok, strange.

So there's ofonod in the maemo-leste already.

user@...uan:~$ /usr/sbin/ofonod -v
1.22

...and it seems to somehow work with the droid 4, in default
configuration, thinking it is "Gobi" modem. 

user@...uan:/my/ofono$ sudo python2 test/list-modems
[ /gobi_0 ]
    Features = sms net rat ussd sim gps
        Emergency = 0

...

... and it seems to kind-of work. Even incoming SMSes work, which I
could not get to work in AT mode. Otoh, voice calls do not, so...

Confused,
