Ron's wife has an iPad 2 and he wants to know if upgrading to iOS 7 will be a big deal for her. Leo says that once the iPad is updated, she won't be able to go back. There is an iOS 6 update that covers the gotofail bug, but it isn't covered with the iPad. So Leo says the best thing she can do is just be cautious of her online behavior.
Leo suggests turning on two factor authentication with everything. The Bank, her email, and Paypal to name a few. That way, if someone tries to steal her info with a man in the middle attack, she'll get a notice via text with a code. Then they can't change her password.
