progress is saved if you delete the app. so if you delete and redownload, your progress should be saved and everything will remain from where you left off while you download the new patcher hack on the updated game. i had it deleted for quite a while and i just redownloaded it, to my surprise, everything was still there. you can't update the game via itunes until the patcher for the new version is out unless you want to play it without a hack. i hope i explained it well enough. so just save, delete, redownload & reinstall the hack.
