Hey all!

I have my TurboSIm in front of me and did all the instalation needed. However, at one point of the instructions (http://iphone.simbunch.com/turbosim.php?type=applesaft), the text says:
"Open up an SSh Command terminal and enter the following..."

What is meant by that? I use CYBERDUCK to access the iphone. Is an SSH terminal a sort of special application?

Thanks and best regards
