We hate to put a damper on those jubliant folks that are celebrating the unlocking of the iPhone 3GS but we have no choice. Looks like a worm is doing the rounds and effecting the performance of jailbroken iPhones in Australia. The worm has been created by a hacker called ikee who took advantage of the fact that the default password for jailbroken iPhones is "alpine"! The worm after creeping onto an iPhone system changes the wallpaper to a photo of Rick Astley! Why Astley you ask? There is no accountng for taste we answer!
