actually we doing native EF handling as well. The whole directory
structure and all fancy difference between 2G and 3G SIM cards. oFono
does way more than any other open source telephony stack I have ever
seen. And we do get these things right, I might add :)

Just have a look. You might be able to re-use some parts since the whole
code is actually in C. Or at least get you started somehow. Depending on
what your goal is this code might be useful or not. It is somewhat tight
to our way of handling modems.

Regards

Marcel
