I sshed into iPodTouch, and looked through /System/Library/Framesworks/*.framework. But I can't find any binary file of those framework. For example There is no "UIKit" binary in /System/Library/Frameworks/UIKit.framework directory. Does any body know that how app find these the binary of standard framework? Or where is these framework binary installed inside ipodtouch?

My device: iPodTouch 4.1, the firmware is 8B117. I did jailbreak with limera1a.
