Remember that whole "Rovio Account" thing Rovio announced not so long ago? You know, the thing that would give players the ability to sync their progress in Rovio games across a range of phones and tablets? That thing. It's out now for Angry Birds [$0.99 / Free / $2.99 (HD) / Free (HD)] on Android and iOS devices.
While using the service, you can pick up and play right from where you left off, even if you've got an Android phone and an iPad -- provided you still haven't beat Angry Birds. What's with the hold up, man?
