so my sister gave me her iphone 3g. and i had a 2g. And my friend gave me his itunes account and i downloaded plants vs zombies of it. And i played the **** out of that game and i want to transfer my save file. So now i backed up my phone and restored it the app wont start up, it just goes to the Popcap screen and goes back to home screen. I deleted the app and reinstalled it and i lost all my stuff. Is there a way to delete the app at the same time having my save files inside?
