The last time i unlocked my phone i had this very same problem, for whatever reason, Ste's site won't let me download the .zip file that contains open ssh client and server. The link to the package is here:
http://ste-pkg.org/iphone-apps/zips/openssh-4.6p1-1.zip

according to the repository, but it won't download. Does anyone have a backup copy or know another place i can get it?
