I have noticed that if I delete an app on one of my iOS devices, I receive a notice warning me that all data will be deleted from the device. I was wondering, is there a way to delete an app, say within iTunes and not directly on the iOS device, and keep the data stored in backup? I ask this as I am running out of space on my iPad and don't want to delete any of my games in fear of losing my in-game progress. I figured down the road, if I ever wanted to play a previously deleted game, it would be nice if my save data was still available. Thanks.
