In Xcode, you can view all the header files of the cocoa-touch framework, but I'm just curious to see what some of the implementations look like. Is there a way to see them? They must be on the system somewhere, right? The header doesn't do anything without the implementation.

The implementation files are compiled into libraries (binaries) and only the header files are provided. They are your contract or entry-point into those binaries. The iPhone SDK is currently closed-sourse so you won't be able to get access to the implementation files, sorry.
