A hacker has discovered that iPhones running the iOS 5 operating systems have a hiddenmode, which allows users to take continuous photos while panning the camera from left to right.
The Easter egg was found by, who describes himself on his Twitter profile as 'Programmer. iPhone hacker. Geek'.
"I found out how to enable Panorama is the iOS Camera app. Set the key 'EnableFirebreak' to YES in com.apple.mobileslideshow.plist," he tweeted.
The discovery of the new feature comes as great news for iPhone users, butmight not be so pleased because it's a function that is still not officially ready for use, the Daily Mail reports.
It is believed that the panorama camera mode is currently undergoing testing before being enabled for general use.
To turn it on your iPhone would have to be jailbroken or you will need to have developer access.
Apple does not recommend jailbreaking the phone, as this can violate the warranty and can cause the iPhone to become unstable and not work reliably.
