I have updated both iTunes and ios. Apparently, when I was given the option to sign up or into iCloud, I did not take it. When I follow the instructions on the Apple website (click settings on iPad and click on iCloud to make changes), the iCloud is grayed out. I am unable to access it. I have obviously missed something here. Can someone - anyone? - help me? I am teetering on the edge of the iCliff!!! Thanks!
