can anyone direct me to the map where angrybirds keeps the save games?

I think its anoying that the save games are so deep in the system and are not in the backup. now when something goes wrong you loose everything if you dont know how to copy the saves.

Its strange that such a highend device doesn't keep saves on a central place. for example in the a map called savegames on the n900 memory so that they can easily be copied to a pc when you need to reflash.
