I followed one of the several tutorials online on how to change the background in Cydia/Settings,
I created a folder called CydiaAppleWP, created a folder inside it called UIImages, and placed the wallpaper I wanted to use here and name it UIPinstripe.png
I SSH'ed them to var/stash/Themes.******, loaded Winterboard, selected 'CydiaAppleWP', resprung, and then went into my Settings app and the new background was there, so I went and loaded Cydia, but alas I get the original old background
