Never tried it myself, but you could try downloading the suitable S60 C++ SDK (Software Development Kit) for your phone and copy the file to the emulator directory on the PC (and then use the emulator and its Contacts app).
The SDK you can find on http://forum.nokia.com (it'll be a pretty big download).
