An iPhone hacker has discovered that iPhones running the iOS 5 operating systems have a hidden panoramic camera mode.
It's great for snap happy iPhone users, but Apple might not be so pleased because it's a function that isn't officially ready for use.
Once it is switched on users can take continuous photos while panning the camera from left to right.
The Easter egg was found by Conrad Kramer, who describes himself on his Twitter profile as 'Programmer. iPhone hacker. Geek'.
Yesterday he tweeted: 'So, I found out how to enable Panorama is the iOS Camera app. Set the key 'EnableFirebreak' to YES in com.apple.mobileslideshow.plist.'
