As an Angry Birds lover, I have always been slightly disappointed by the fact that when both me and my wife share the same phone to play the game, we never know who set the highest score in every level. Short of splurging the green for a new phone (she is still under contract with her crappy Pre), we now have another option - a small utility wittily called Angry Aviary.
utilizes its elevated privileges (your phone needs to be rooted) to swap Angry Birds profiles around on the fly, thus letting multiple people go through the game at their own pace. I've just tried it, and it worked flawlessly - after creating a new profile and switching to it, all Angry Birds levels went back to locked state with 0 stars.
