I have been using 1Password for several years now and a while back in anticipation of getting an iPhone, I got 1Password 2.2.1 for iPhone but never used it. (Not sure whether it was free or part of an upgrade deal.)
Now I have an iPhone 4 (iOS 5) and would like to install the latest version of 1P. When I go to the App Store, it says there is no update available.
Could someone please let me know what the upgrade path is?
