Ok, all the winners have been notified, either by PM or direct Tweet.
IMPORTANT: Non-US people, you will need a US itunes account. Here’s what I recommend you do to get the app on your phone. I’ve never done this personally, but it should work.
1. Create a US itunes store account. To switch stores, scroll to the bottom of the page.
2. In itunes on your computer, switch to your new account, make sure you are using the US store and redeem your code (click redeem on the home page).
3. On your phone, go into ‘Settings’ for the App store / itunes. You’ll notice you can switch accounts. Switch to your new account
4. Go into the app store on the phone and try to buy / install the app.. It should tell you that you already own it and install it.
5. Once installed, switch back to your regular apple itunes account.
