I have a case open with Apple regarding this issue and received this response:
"I have received word from the Engineers. So, the Engineers they have reviewed all the documentation and the emails and video you sent me and determined that the EXIF data on them (the pictures) is correct. The issue they feel, is not with the photos but rather the viewers of the photos the customer is using. No, they are not meaning you or the friends that are viewing the photos so don't be offended, I know how that sounds. What they are referring to when they say the EXIF data is the data attached to photos that includes information like the orientation, size, origin, camera maker, etc.. Since I am not familiar with 'viewers' or what the viewer is on an iphone I have sent a reply asking for more clarification on this and will contact you as soon as I have more. I apologize I do not know more at this time but I am still working on it. Please hang in there while I attempt to get more information. "
