I have loads of apps where everything useful is just stored on the services servers, such as Chrome, Twitter, Dropbox etc., so it's almost pointless having these things backup to iCloud other than to save the login details. So, if I turn these off, do the apps still download but without their data, or do they not download at all and iCloud just acts as if it was never on your device? Also, I've noticed that even when I've deleted apps from my device, they still show up in iCloud. Is it supposed to do that? Perhaps to restore if you decide to redownlaod it?
