Angry Birds To Sync Across Platforms

I play Angry Birds on my iPad and on my Android phone. Because there is no way to synchronize my progress between the two devices, I only play the original version of Angry Birds on my iPad, and the Seasons and Rio versions on my Android smartphone. Rovio has revealed in a tweet that they are working on the ability to synchronize across all platforms, which will enable me to not worry about which device I play the game on.
