Adding extra fields for an AddressBook contact using iphone simulator

I was new in iPhone application development. As i might have gone through native applications, i was struggling from 1 week, for adding new fields to a particular contact of AddressBook.

As we might have known that it is not possible to edit addressBook details, i want to bind those values to sqlite3 table & then i thought to add new fields to select开发者_Python百科ed contact.

Can anyOne of you push me out of this situation..? (Plz,provide me with the Sample Code to test.)

Note: AS I have no device,i need to test it using iPhone Simulator. Let me know, would it be Possible or not?

Thanks & Regards,

Ramya.
