An Australian has released a virus for the Apple iPhone, 'ikee', which replaces the infected device's background picture with an image of singer Rick Astley.
Security companies Sophos and F-Secure have issued warnings to owners of jailbroken iPhones to change root log-in passwords immediately. All iPhones are issued with the same root log-in password.
