I have attempted to follow the directions you provide in order to import data I have in version 3.5.9 on my iPhone to the version I acquired today. When I open the new version on my phone I get the error message "Import failed. Database is invalid". Most other apps automatically important data from a previous version when you acquire a new version of the same app so why the complicated steps with your app? I have 98 individual accounts with passwords that I'd rather not have to manually enter.
Also, I sync my iPhone with my iMac (so there is a backup of the 1Password data on it) but I can't figure out how to get that data into the new version that is also on my iMac.
