Iphone Gyroscope Problem

When I go to Photos, Safari, Ipod and every other app that uses the Gyroscope of the Ipone 4, I cannot move the picture.
For example when I am on photos and want to look at a picture in landscape view, I cant. I can only view it in portrait view. I move my Iphone in every way possible and nothing. I tried to reboot the Iphone and nothing happened.
I will send my Iphone to Apple if nothing works because this is a 2 week old phone!
