new iPhone 4 user has questions

on the status bar to the left of the batt, there is a lock in a circle.... I'm guessing that I have somehow turned on a lock that is preventing my photos from turning to a horizontal position. Can anyone tell me where to turn it off? I can't find any ref to it in the manual. Thanks for any help.

Double click the home button to pull up the multi-tasking bar. Slide ur finger over right to reveal the ipod controls and a little button on the left that locks your position.
