Rotating a photo erases most of the metadata

[demoend]

When I rotate a photo using the 'Photos' app in iOS5 most of the metadata in the photo is lost.

How to reproduce...

Take a photo using the build in 'Camera' app, I'm doing this on a iPhone 4 running iOS5.0

Use another app to look at the metadata of the photo (such as MetaBrowser app or the ExifWizard app).

Notice there are about 40 different types of metadata stored in the photo. Such as the make and model (Apple/iPhone 4).

Now use the built in 'Photos' app to rotate the photo you took and press the 'save' button.

Next, go back and look at the metadata again of the photo.

Make sure you restart the app you are using to look at the metadata so it has the latest changes.

Notice there is now only about 10 different types of data stored in the photo.
Lots of the good metadata is missing. such as the make and model.

I suspect rotating the photo should preserve all of the metadata?

Hmm, it should. Have you tried seeing if "enhancing" and "red-eye reduction" also loses the data? If so, this is something that Apple definitely needs to fix for me to want to use the onboard photo editing.
