While the majority of the iPhone's easter eggs and secrets have over time been discovered, pulled apart and analysed to the umpteenth degree, the smartphone continues to have one, little-known trick up its sleeve: A hidden serial port. The inherent possibilities are endless: Network engineers have talked of even bringing their phone into server rooms, rather than having to use a laptop or remote terminal.
According to Chris Pollock at [[xref:http://www.ionetworks.com.au|io Networks]]: "the real benefit in all of this is that there are so many console packages for iPhone in Cydia now that you can have a fully functional computer, as useful as a linux box, but without carrying around a laptop".

Pollock compiled a step-by-step guide to do exactly that, thanks to his own handiwork and the diagrams at [[xref:http://pinouts.ru/PortableDevices/ipod_pinout.shtml|pinouts.ru]]. We reproduced it here with his permission.
