When I take pictures with my iPhone 5, I get the black bars so it's the size of previous iPhone screens. Is this normal or is there a setting to make them 4 inches? I never thought about it before but I just saw the iPhone 5 commercial that highlights photo streaming and all of the pictures are the size of the full screen. I realize that Apple can do whatever they want for their commercials but I wasn't sure if it was that or I could actually take 4" photos. Thanks for any answers!
