Angry Birds Christmas Edition Is Free Upgrade for Halloween Edition

Love Angry Birds, like we do? Have you downloaded the $0.99 Halloween version of said mobile game? If yes, the "Christmas" themed version of the game will become available to you, for free, as an update in the near future.

And good news for Android users: This version will not be an iOS exclusive like the Halloween version was last month. [Mobile Burn via TUAW]
