My iPad started to auto-command itself. First some extra letters when writing a note, then scrolling the page. Now closing software and opening another by it's own. Now the latest thing is that if I open my notepad, it starts erasing the text and typing something else on it =( This is my first mac, and I've always thought that no anti-virus is necessary. Or is it? My iPad is NOT jail-broken, and I've downloaded apps only from Apple apps store. What is going on?
