I just got a pocketbook iq for christmas and i'd like to stay logged on to facebook and my email account but i can't find a way to password lock the device. I'm very paranoid and i'd like to think my accounts and data are safe and i need passwords for that. Am i missing something or is it really not possible? Is there an app out there for adding passwords? I really liked this ebook reader up until now but this just ruined everything
