Looks like we found another iPhone 4 oddity. It looks like taking and sharing pictures with the iPhone 4 may have a couple of bumps in the road. The iPhone 4 uses scantily-supported JPEG orientation flags for photos rather than actually rotating the pixel data, causing many online services (Dailybooth and Facebook included) to interpret portrait-oriented photos as landscape and then turning them on their side. As you can see above, I took a self-portrait and sent it in to Dailybooth, and it appeared as a landscape image.
