I FOUND THE ANSWER ON YOUTUBE!!!!
If u have a padlock icon on your status bar with a circular arrow around it, you are locked in portrait mode! This can be turned off by double clicking home button (this will bring up any apps etc you have open) scroll them to the right so the section with the ipod icon play buttons etc a visable, the far icon on the left is the button to toggle this function.
Where are we newbies supposed to learn stuff like this??????
