Fixing Anki Flashcard Dates

I've been using Anki for a while to learn things.  Recently I made the mistake of editing some existing cards to have a new meaning.  The problem was that the algorithm for when the card would be next presented to me did not reset itself on the edit.  I was left wanting to see the edited card, but Anki telling me that I'd have to wait for three months first.

Here's how I fixed it:

1. Installed the full PC version of Anki:  sudo apt-get install anki
2. Connect the full PC version and sync up the deck in question
3. Realise that the Debian stable version of Anki is out of date to work with the server
4. Set up Apt-Pinning for Anki:
1. Add a testing entry to /etc/apt/sources.list
2. Edit /etc/apt/preferences and set it up like this

Package: *
Pin: release a=stable
Pin-Priority: 900

Package: *
Pin: release a=testing
Pin-Priority: 600

3. Run aptitude, update
4. Find the anki package in the aptitude UI
5. Pick the 2.0... version of Anki and install it -- being careful to make sure aptitude picks the correct version
5. With the PC client running click "browse"
6. Select the required deck
7. Select all the cards
8. Do Edit->Reschedule then set the schedule for zero days
9. Close the browser and reopen the deck, all the cards are now ready for review
10. Sync back up to the server and back down the phone again
