There is an awesome app for the iPhone Android called i3DSteroid that allows easy photographing and creating 3D photos with your mobile phone that auto aligns and saves in various 3D formats. Parallel Stereo photos or 3D Anaglyph Cyan-Blue.
The app needs some interface refinement, but it works perfectly.
