I have root access to my phone, so r/w access isn't going to be a
problem. I also have SQLite installed (as a dependency of some other
port(s)) on my home computer. I will try this during the weekend. If
I'm not mistaken, you and I are in the same TZ, which means we're both
up so late it's actually early... Suffice it to say, I'm not up for
the task right now. I'll report back once I've tried it.
