I have used iPhoto to backup my pictures from the iPhone. How can I find all the iPhone-photos without having to click on all the pictures to view the EXIF-info?
You can create a smart album with a condition on the camera model (Camera model includes "iPhone").
It's even possible to select the front or rear camera by adding a condition on the aperture. See this hints for details.
I believe iPhoto '09 has this - the picture above is in iPhoto '11 and it works great there.
