日前，芬兰开发商Rovio Mobile在回复用户的一则Twitter微博时表示，将面向已购买0.99美元《愤怒鸟》万圣节版本的iPhone、iPod touch和iPad用户，推出免费的《愤怒鸟》圣诞节更新版本。

不过，Rovio并没有透露该版本是否将像采用AdMob服务的《愤怒鸟》Android免费版本一样，选择iAds作为iOS免费版本的广告赞助方式。对700万已下载《愤怒鸟》的Android用户来说，另一个好消息就是，该游戏圣诞节版本不再像万圣节版本一样仅针对iOS平台，很有可能面向其他平台用户开放。（本文为游戏邦/gamerboom.com编译，转载请注明来源：游戏邦）

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. （source:tuaw）
