Angry Birds and Angry Birds Seasons both got updates on iOS last night. The smaller update is the regular Angry Birds, which has been updated to 1.5.2. The 1.5.1 update brought new badlands and the Mighty Eagle but there are no new levels in 1.5.2. This update just brings a custom settings panel under the system settings which allows enabling/disabling of notifications and language changes. According to a tweet by Rovio Mobile, developer of Angry Birds, the next update, 1.5.3 will have new levels but they haven't specified when this update will be out.
Go get your pot of gold
More excitingly, Seasons finally has its luck o' the Irish update. It has 15 new levels as well as 3 additional “Like Us on Facebook” levels like they did in the last Seasons update (Valentine's Day edition) as well as two new golden eggs and pigs in leprechaun hats! The update seems to be out only for iOS right now and Rovio tweeted at this reporter saying that the update for Android will be here “really soon and Symbian later”.
