human-readable import/export of SMS on sailfish is mission critical before i can start using jolla as a primary phone. likewise with call log and contacts {MMS would be nice too} i also dont care what format is used, as long as its human-readable, well-structured, and validatable. however, i personally would prefer a platform-independent solution, preferably one that just reads/writes the sqlite database so that it can be done on a faster box.
as soon as i get a jolla {usa, so sad} this will be the first thing i investigate coding up. -a sqlite solution will be complicated. it will also be brittle, since the libcomm interfacing impl and the sql table structure could change -things aside from libcommhistory might be in the sqlite db, so this might involve risk in replacing the db. -if the jolla code that handles the sqlite db is open and modular, it might be adaptable for this purpose
