Actually, this is pretty much a useless answer as, if the iPad is online at all, it will just download the update again and start nagging again.
Apple, in their infinite stupidity, can't think of a reason to not update. Well, I can.
I am saddled with this iToy for work. It has apps related to flight safety installed. Until the IT department can confirm that all necessary apps will function with the update, we can NOT install it. We can, however, be continuously nagged because someone thought it would be a good idea, and an even better (read STUPIDER) idea to prevent users from turning this annoying feature off! We can also face the risk that one unfortunate tap will cause an update we don't want, and worse, may make the iPad useless just as we initiate an approach at a foggy destination and we are trying to bring up approach data.
Blocking the Apple server is not an option, as we use these on various wifi systems around the world. Turning off wifi until the update is approved won't work, either, as it is necessary for loading flight plans, viewing documents and updating other time sensitive flight data.
So, does anyone have a real solution?
Barring that, can anyone find the twit responsible and line him or her up against a wall?
