How to move code signing certificates to a different computer.

This was a great link that got me most of the way there.  http://www.theevilboss.com/2009/06/iphone-sdk-development-on-multiple.html

However once I installed everything I got this error.  “a signed resource has been added modified or deleted”.  After spending a while double and triple checking everything, I did a clean all targets and rebuilt and had success.
