DTMF + Arduino + Sony Ericsson test

The video shows a test of the control system for the DTMF "robot" that I'm building. The Sony Ericsson phone is connected via serial to the arduino. The arduino takes reads input from he DTMF IC that is conected as a hedset to the phone.
When I call the phone the arduino answers and flashes the light. When the DTMF BOT is done the keypad on he remote phone will control servos witch moves the BOT. But for this test the [5] key turns a LED on and off. When the LED turns on i also sends a AT-command to the phone to turn it's flashlight on.

I will post info about the project on this blogg: http://oscar.crf.nu/

Hi!

I have to say that this project looks realu interesting :) I'm trying for days to connect my SonyEricsson via serial to Arduino but I was not lucky :( Can you share the connection schema, please? Is there a need for any aditional electronic to make serial work? Any special coding trick?

Thansk :)
