Agile just released 1Password 4.2 for iOS and it is a really nice update:
Better Browser Go & Fill Bookmarks are now in 1Browser on iPad. (The iPhone is coming.) Also, if 1Password sees a URL in the clipboard, it’ll prompt you to open it in the 1Password browser.
Better Sharing You can share 1Password vault items (encrypted) with others. This will make things much easier between myself and MrsMacSparky.
Better Search Search in iOS 1Password now searches all fields.
