I realize this answer comes pretty late, but perhaps it will help others who land here. If you get another iOS device, you can restore the 1Password backup on that iOS device.
That backup format is not currently compatible with the Windows version of 1Password, unfortunately. It is compatible with 1Password for Mac, however, so if you have a Mac and can download the free trial of 1Password for Mac, you can restore the backup there and then sync with Dropbox.
