PrivateFrameworks - iPhone Development Wiki

Private frameworks are frameworks which Apple intends for use only by Apple's own apps. Private frameworks are more unstable than public frameworks between iOS version updates, but many of the interesting features of iOS are in the private frameworks.

Attempting to use private frameworks in an App Store app means that Apple will reject that app.
