I can't figure out how to save the files in "/System/Library/PrivateFrameworks/Celestial.framework/".
I can save files in "/var/mobile/Library/Preferences", but I can't save files to "/System/Library/PrivateFrameworks/Celestial.framework/" programatically.

Is there any way where I can save a file to that directory without changing the permissions/owner/group of the file that I'm writing to. If there's no way to save to the file without changing those attributes, what must I do in order to save to files within that directory?
Thanks

why don't you modify it on your computer, then use winscp to drag it to your directory on iPhone?

haha I know how to do that.
But I need to modify a file that is in "/System/Library/PrivateFrameworks/Celestial.framework/" programatically. That means use an application to modify it and save it, instead of manually modifying it and then uploading it back.
