Not an iPhone user, but I wonder if you could access the key data manually and restore it afterwards?

On Android that's possible (if you have root....) by accessing the key database (sqlite in that case). I did that to duplicate the keys from my handset to my tablet.

Yes, if you have synced with iTunes before the update. If that's the case you have to delete the updated app from the phone, connect phone to iTunes (do not sync or transfer purchases) and copy over the old app from iTunes to phone and it will restore the old version + app data.

didn't work for me - app was restored but not data

Restoring from an iTunes backup should restore both the old version and the app data.
