Preview at WWDC likely in June, followed by September launch.
Hidden iOS 5 Panorama Mode Revealed
iOS developer @conradev revealed on Twitter that he had been able to enable a hidden "Panorama" mode in iOS 5. The setting can reportedly be enabled by setting 'EnableFirebreak' to YES in com.apple.mobileslideshow.plist. iOS developer @chpwn has already submitted an app to Cydia to enabled the panorama mode for Jailbroken iPhones.
Clearly Apple had been testing the Panorama mode as a possible feature for iOS 5, but for whatever reason it didn't make the cut into the final release. The user interface shows that a user can capture individual photos from left to right and the software will stitch it together.
Apple did introduce a number of other new features to iOS 5's camera app, including grid lines, pinch to zoom gestures, volume button shutter and editing features.
