SSH stands for Secure SHell.
It is just a protocol that allows you to access your iPhone or iPod Touch from your desktop PC or MAC and execute commands on it (thus allowing you to copy any kind of data to and from the iPhone or iPod Touch without iTunes). It’s also used for a lot of customization things if you know what you’re doing.
You can use a program like Cyberduck on MAC or WinSCP on Windows and you can browse your iPhone or iPod Touch like any other hard drive and explore it’s content (which can be very interesting).
