The simulator uses OS X libraries like libSystem, CoreFoundation and Foundation; and the iPhone-specific libraries are implemented differently, as emulators over the native functionality. (For example, the Keychain library in the simulator just wraps the entirely-different OS X Keychain API.)
Also, the simulator runs x86 code where the iPhone is ARM, which will introduce some differences. (Is ARM little-endian?)
