from the Daily Mail UK:
World's first iPhone virus changes your wallpaper... to a picture of Rick Astley, hacker claimsBy Richard Shears
A 21-year-old Australian claims to be the first hacker in the world to infect the iPhone with a virus.
It spreads between phones with each call but the damage extends to changing the device's wallpaper - to a photo of Eighties pop star Rick Astley famous for his hit Never Gonna Give You Up.
Sydney student Ashley Towns said he wanted to raise the issue of security, adding: 'What I've done has shown that anyone can easily hack into an iPhone.'
He added: 'The virus pretty much exploits people's laziness in not changing their password.'
Rick Astley is a popular choice for mischievous computer users.
Video-sharing website YouTube has spawned the phenomenon of 'Rickrolling', where a person provides a weblink to an innocent-looking topic but this actually takes the user to a video of Rick Astley singing 'Never Gonna Give You Up.'
Mr Towns' virus can only infect iPhones which have been 'jailbroken' by their owners - an action that allows phone owners to install applications on their phones which have not been approved by Apple. .........(more)
