Instagram today updated its iOS version to 4.0.2 which allows the iPhone, iPad and iPod touch users to capture and shoot photos and videos in Landscape mode. You could only take portraits with the earlier versions.
The now updated Instagram for iOS also has a Cinema mode support for devices with front facing cameras. The Cinema mode uses advanced stability and adds nice effects to your video even if your hands shake. The video may appear slightly cropped but its far better then a shaking and jerking video.
If you own a iOS device, head over to Apple Store and download the updated version now.
