Just got mine, so I can attest that it's legit. But it's Facebook, so YMMV.To participate in the Christmas Giveaway You need a Facebook account. Offered by Sony, this app asks you, among other things, to subscribe to the Playstation Europe updates to share the app on your Wall or to spread the news on Twitter. For each action performed, you'll get a code that you can redeem on the PSN for one of these PS Minis.
