The first worm to infect the Apple iPhone has been discovered spreading "in the wild" in Australia.

The self-propagating program changes the phone's wallpaper to a picture of 80s singer Rick Astley with the message "ikee is never going to give you up".

The worm, known as ikee, only affects "jail-broken" phones, where a user has removed Apple's protection mechanisms to allow the phone to run any software. Experts say the worm is not harmful but more malicious variants could follow.

"The creator of the worm has released full source code of the four existing variants of this worm," wrote Mikko Hypponen of security firm F-secure. "This means that there will quickly be more variants, and they might have nastier payload than just changing your wallpaper."

The picture of Rick Astley is believed to be a nod to the internet phenomenon known as Rickrolling, where web users are tricked into clicking on what they believe is a relevant link, only to find that it actually takes the user to a video of the pop star's song "Never gonna give you up".
