Great! I am cc'ing Nick and Stephen from Zetetic, who maintain SQLCipher
core, and are fully involved in the Android edition, as well. I am going
to answer, but hopefully they will chime in, as well, to enhance or correct.

I think what we have shipped right now, especially the recent ICS
update, is good enough that we want people to be spreading the word.
SQLCipher 2 is mostly under the cover improvements around cryptography
and performance, and very little will change from a developer standpoint.

The only progress we have made on this is through our NoteCipher sample
app, which has some best practices helper code in it. You can start by
We also have some much grander R&D going on related to key storage and
management across devices, that includes some potential work in this
area over the next three months. However, currently we are mostly
focused on OpenPGP and OTR, and not SQLCipher as much.
Thanks again, and glad to have your valuable support and interest!
