Alright. I recently bought and iPad from my cousin. Immediately after I got it, I logged out of everything and reset all the settings. I went into settings and put in my Apple ID and then I went into the App Store (and iTunes Store) and made sure my ID was the one in the little box at the bottom (it was) . Then, when I tried to update an app, my cousin's Apple ID popped up and it was asking me for her password. So I signed out and back in on everything -- literally everything -- and it's still doing it. I don't know what to do. Help is greatly appreciated!!
