I just found this while getting my morning dosage of Slashdot.

A site called "allpinouts.org" is built on the theory of providing hardware pinouts to many different types of equipment such as PDA's, Cellphones, modems, etc.

The intent is to give the basic information needed to allow for hardware hacking of electronic devices. What a cool idea!. For more information please visit the slashdot story at http://tech.slashdot.org/story/09/06/22/233210/A-Wiki-For-Cable-and-Connector-Pin-Outs?art_pos=2

I'm linking the site off on mine for future references. http://www.allpinouts.org/
