Broken iCloud sync between iOS 4.5 and MAS 4.3 and how I fixed it

With great excitement, I downloaded updates for MAS- and iOS versions yesterday. Only to find out that the sync between iPhone/iPad and Mac was broken. Between the two iOS units everything worked fine. And the was no welcome screen or walkthrough when restarting the updated apps.
Here's what I did. I you choose to do the same, it's on your own risk of course.
iPhone/iPad

• Disable iCloud sync in iOS apps.
• Close/force quit iOS apps.
• Disable iPassword in iOS Settings/iCloud/DocumentsData/1Password

• Delete app from iOS device

  Mac

• Backup 1Passw in Settings/backup

• Turn off 1Passw Mini in Settings/general
• Deactivate iCloud sync in Settings/Sync/Change sync. Remember to tick "Remove data from iCloud".
• Quit app.
• OSX Settings/iCloud/Documents and data (options) uncheck 1Password mini
• Navigate to User/Library/Mobile Documents/ and find the two folders ending with "one password-osx-helper" and "onepassword". Trash them.
• Restart Mac. A little salt over the shoulder doesn't hurt.
• OSX Settings/iCloud/Documents and data (options) activate 1Password mini
• Launch 1Password
• Activate iCloud sync

Have a coffe/water/beer/beverage of your choice

iOS devices

• Re-install 1Password
• Enable iPassword in iOS Settings/iCloud/DocumentsData/1Password
• Launch 1Password
• Activate iCloud sync in Settings/Sync

And there I was. Back in my comfort zone.
