MICRONTROLLER TO PIC

Use the 16F690, the '84 is a pre-historic chip! Also, you would only be able to connect to the phone if it has a RS-232 / USART somewhere on the connector, if you want USB be prepared for a PIC24F and lots of coding headaches
 

MICRONTROLLER TO PIC

Hey There is one more Idea if you want to Do such a project then use GSM modem...
