I've just got a new iPad, got 8 updates available on app store, after like 5 min there were 4 updates. It was when I realised that it was automatically downloading stuff, so i disabled it from iTunes and App Stores settings as you wrote. The problem is that even though I disabled everything, every time I reconnect this iPad to wi-fi it continues to download because from 4 available updates it went down to 2. And somehow it managed to download GarageBand update, that's 600mb off of my monthly 8gb!! Why does it keep downloading from app store?
