Ignoring SQLite, I would never expect to be able to go back to an older version of *anything* and have it read the same data files created by a newer version.
If your application were writing its own data files, do you think it would robustly be able to read ones written by a newer application in an older version of it? In terms of SQLite specifically, I also wouldn't consider this a document storage mechanism. It is a database, and good for that kind of stuff, but if you have data you want to transport across different devices I really think it should be in a robustly designed document format.
