I had the same problem with a new weather widget that I downloaded for my lockscreen. It came with a ReadMe file, which I finally found using iFile. I went to /var/stash/Themes.???? and found the name of the theme. I tapped on the theme (not the arrow to the right) and that opened a listing of the theme-related files. I scrolled down and tapped readme.txt, followed by Text Viewer when the viewing options popped up. If you can find that file (if there is one) it might give you a better explanation of the weather widget.

Somewhere in your theme there should be some kind of file related to weather. It might also be listed as a separate theme, eg, MyTouchHDWeather.theme, in Winterboard. If that's the case, follow the above directions to open the weather theme and go from there.
This might not be the exact way to do it for your theme, but maybe it can give you some ideas about how to find the area that has to be customized.
I didn't have to use OpenSSH, I did it through iFile directly on my iPhone. However, OpenSSH and the desktop app that I use (YummyFTP) would have worked.
P.S. OpenSSH doesn't put an icon on your springboard, you have to access it through a console-type application. I use SBSettings, which is free and available on Cydia; I can toggle OpenSSH on and off through SBSettings.
