Er... Does it shoot RAW?I think I remember RAW being available to app developers, from the coverage just after launch. I may be wrong as I can't find said report at the moment.
What Apple have done is to allow manual shutter and ISO setting control. This is not included in Apple's camera app but is in a small but growing number of third party camera apps on the App Store. Meanwhile, here is a test shot taken in my lunch break. HDR was not used.
Edit: I have just found that although the image was rotated in Photo app, it was not when uploaded.
