iPhone Worm for Cracked Versions: Please Change the Default Password

A worm targeting jailbroken iPhones has been spreading in Australia. This is the first virus to appear since the iPhone's launch over three years ago. Affected iPhones will have their desktop backgrounds forcibly changed to a picture of the famous British singer Rick Astley, and the worm can then spread to other iPhones. Since it could be Rick Astley, it could also be anyone else, or even a pornographic film star - who knows who it might be. Cybersecurity experts are urging users who have used JailBreak software on their iPhones to immediately change the default password to prevent infection.
