Seeing the same issue. The EXIF data is just wrong. When I open an image taken with iPhone 4G in Photoshop, the dimensions are backwards, but Photoshop displays it correctly, as does Preview, iPhoto, etc. If I save the image in Photoshop, it corrects the dimensions in the EXIF data, storing them correctly for portrait mode.
The EXIF data is correct. The app displaying the image does not respect the EXIF data. The 'standard' has been to save the image so that rotation isn't necessary when displaying and lazy programmers make the assumption that is always the case. This is partially because not all of the rotation info was available in early versions of EXIF. Today that is no longer true but old practices and assumptions are sometimes set in concrete.
With the iPhone we see that isn't always the case. Apple must have had good reasons for doing it the way they did and I won't speculate on that.
When Photoshop saves the image it adjusts the save so that no rotation is required. The 'fix' is for the programmers to get over their belief that images are saved with no rotation and to actually read the EXIF data and use it to adjust the image before displaying it.
It is a case of Apple being 100% correct but still causing problems for their users because of the outdated systems the users must interact with. I don't like it but I do understand it.
