Last night I updated my iPhone with the iOS 5.1 software. It took a while to upload and install, so I thought there might be some new features. This morning when I turned it on, I noticed a quick access to the camera. It doesn't seem like much, but it could be a nice little feature when you need to capture that spur of the moment shot.
With a quick slide upward of the thumb, you phone goes into camera mode and you are ready for the shot. Can't wait to use it.
