Android and SQLite have had some adventures: pre-Honeycomb (v3/API 11/2011), corrupted databases were automagically deleted by the OS API used to open them!

SQLite was also shaking out a (very) few bugs out during this time period; pretty sure this auto-delete implementation wiped any chance of semi-easily recovering my first phone's SMS db.
