I don't know what you might have to change to get that exclusive access away from the Kindle's firmware while you are playing with the 3G card's command set.

This suggests something, am i right?
While turning off radio Kindle's software wont use it (maybe some AT command to tell hardware 'go powersave' and 'wake up'?), but the device should be available in /dev as serial port. Then it could be possible to send/receive SMS without interferencing with firmware. =]
But wait!
Let's assume what can be done to check possibilities.
Put minipcie modem from K3 into some other device and check... - check what?
There are such modems/devices like one attached (i'm going to look for something like such on my localisation). I can try this out. But still - what will we get to know when i
test it?
Buy another K3 that might go brick and test.
That's quite self-explanable.
Work on my daily-used K3 and hope it won't get broke.
Ok, lets assume i won't modify rootfs (now i'm quite sure i won't):

The Kindle's firmware expects to have exclusive use of that internal USB connection to the 3G card.

It probably won't be angry if i'll try to send some AT commands, and it wont blow up into my face, huh?
BTW. many thanks for such a long conversation and answers. i do not know if it will be used by anyone else except me, even if it works so... thanks. apreciate that.
