The first worm written for Apple’s iPhone has been unleashed and is infecting phones in Australia. The worm, known as Ikee, is only a threat to users who have jaibroken their phones to run unauthorized software. It changes the victim’s wallpaper to a photograph of 80s singer Rick Astley and then seeks out other phones to infect. “There is a real danger that someone could take this code and make it do something malicious,” a security expert says. It does not affect most iPhone users; only those with jailbroken iPhones with default password.”]
