Ok. So basically, if you enter *#06# you get the IMEI. So, did it used the
dial / phone functionnality?
When you say "communicate" is it similar to RPC calls? When you ask for
accessing the stored sms's, does the BP send the files directly to the
userspace app calling for it?

... but with the 2.6 ? I guess that the EZX proprietary SDK handles the GSM
functions calls, right? How would we do it then on OpenEZX? Do we have to
implement the SMS app? Everything related to GSM operations?

So you're saying it's standardized? For instance the "gimme my IMEI" thing?
Just another question:
Can one redirect the audio stream coming from the mic ? Or/and put an
arbitrary audio stream on the line?
Before: mic <> BP
After: mic < encryption > BP
We could do pgp-like authentication (or even encryption), then... Or, if it
is possible to handle a data connection AND a voice communication at the
same time, authenticate with pgp with a challenge...
