Angry Birds Christmas to be free upgrade to Halloween edition

Rovio has a free gift on the way for everyone that ponied up the $0.99 for the Halloween edition of Angry Birds. The promised Christmas edition of the super-addictive mobile game will be a free update for iPhone, iPod touch and iPad users. @RovioMobile responded to a query on Twitter confirming that the next edition of the game will come gratis.

Rovio has not yet indicated whether it will start incorporating iAds into the iOS version of the game and giving it away as they have done with the AdMob-supported Android edition. Fortunately, the 7 million Android users helping the birds recover their eggs will be glad to know that the Christmas add-on will not be an iOS-exclusive like the Halloween edition.
