Frameworks are folders each containing a dynamic library and resources for that, library such as images and localization strings. All frameworks have the file extension .framework.

On the iPhoneOS there are 2 kinds of frameworks: public frameworks and private frameworks. Public frameworks are those ones endorsed by Apple and are allowed to be used in AppStore apps. Private frameworks are intended to be used only by original apps, and are more unstable against firmware changes, but many of the interesting features are in the private frameworks.

Public Frameworks

All public frameworks can be found inside /System/Library/Frameworks/.

Private Frameworks

All private frameworks can be found inside /System/Library/PrivateFrameworks/. The descriptions may be incorrect, since most frameworks are not documented after all.
