The iPhone is designed to fully integrate with Apple computers such as the MacBook Pro, which is why it's so baffling that you can't transfer your iPhone camera roll to your Mac directly through iTunes.

Mac OS X provides two solutions for downloading photos from your iPhone's camera roll: iPhoto and Image Capture.
Turn on your iPhone and connect it to your computer.
