I'd like to be able to disable iOS downloads when connected to WiFi.
We are going to Europe next summer, and are renting a MiFi device to support 2 iPhones, and iPad, and a laptop. A full iOS download would wipe out several days of our bandwidth allocation.
I know how to disable application updates. But, I currently can't disable the automatic iOS download.
iOS updates should only download when connected to wifi AND an external power source. I would suggest putting your device in Airplane mode while it is charging.
