Sophos, the anti-virus company is reporting about a possible infection for jailbroken iPhone of the Rickroll worm that changes the iphone wallpaper with the picture of Rick Astley, it appears to be a proof of concept, but Sophos is recommending to all iphone users with jailbroken ipod touch and iphones that change their default password.

The rickroll is not a malicious worm, but jailbreakers should take notes about this concept and protect their devices.
