I just got my iPhone 4 and it won't go to landscape orientation?

Is there any way i can fix it. I already went to the multitask page thing, and it said it was unlocked so I'm not sure what to do.

Just push it again, try to turn it, if it doesn't work push it again. It should fix it.

Double Click the home button. Swipe from left to right. Make sure that the Orientation is not locked and voila!
