> IIUC, iPhones support whole disk encryption as a standard feature,
Last I checked iOS only allows applications to store some (all) their data encrypted. As they have to specifically request it (maybe even with a hard-to-use API), many applications will not do it.

Huh, a cursory google suggests that you're right, and that's still true.
Though I guess this makes some sense -- if you have the phone turned on but locked in your pocket, then the disk itself needs to be accessible (because the OS is running), but you would like the actually sensitive data to be encrypted with a key that you can throw away when the phone locks.
