Full backup (ie: app data) for unrooted GNex? This may be a stupid question, but anyways. As good as the phone is, I don't see myself keeping it for the rest of my life and will need to upgrade. With that, I'd rather not go through hundreds of puzzles/levels of games and enter info into apps all over again just for changing phones. Is there anyway to do a full backup with app/game data as well on an unrooted gnex? I haven't looked into rooting much other than when I first got the phone finding out that rooting one will wipe whatever data you have on there.
