What always bugged me, before iOS 5, was that I had to sync all those apps installed on my iPhone and iPad to my Mac, for various reasons: it takes away space (around 20GB, which is a lot on a small MacBook Air SSD), everytime an app gets updated, it had to be transferred again, and you can't use those apps on the Mac anyway. But I did it, so I had a backup of the app data. Now with iOS 5 and backup to iCloud, all app data is being saved to iCloud. There's no need to keep syncing apps to my Mac. So I tried disabling app syncing in iTunes, but there's no option to stop syncing but leave all the apps installed on the iOS device. It's either keep syncing, or stop syncing and lose all your apps, and, more importantly, all app data. If it was only the apps themselves, I could download them again, but the deletion of app data is the real killer. Is there a way to do that? Would it work if I stopped app syncing and then restored the iOS device from an iCloud backup? Would I get to keep the app data?
