Lost apps like (settings, camera, pictures etc.)
II've lost apps on my ipad that you can't normally erase!! I have also lost apps like twitter, spodify, and yotube! I don't know what happened. The apps such as Youtube and spodify etc were white and so I tried turning off my iPad and turning it back on. Then when I turned it back on the apps were totally gone! I don't know how to get them back and I can't updare my ipad if that's whats needed!! Any help?!? Please?!?!?
