Unlike feature phones, smartphones like the iPhone run on operating systems, which very much like our computer have administrator privileges.
It is hence that when the hackers get access to your iPhone's administrator account, they can lay their hands on anything that is on the iPhone. However, in a non-jailbroken device, this administrator account (called root) cannot be accessed as the iPhone has no console or terminal access and also does not run services like SSH.
But when an iPhone is jailbroken and SSH is turned on, it becomes imperative that you change the default password of your root since hackers now have an easy access to your iPhone. Here is a short guide on how to change your root password.
