Could you submit patches using git send-email?  Otherwise I can't apply 
them.

Lets go through the changes one by one:

I really think this part is not necessary.  oFono expects autoattach to 
be disabled.

On older Telit firmware, CFUN=4 turns the SIM off.  If you have such 
firmware, I suggest upgrading it.  Otherwise the modem will not work as 
oFono expects it to.

This change should not be required with latest firmware.

ICCid changes should be in a separate patch.  I'm not sure they are 
still required with new firmware.
