Adruino Mega and K810

Hi!
I am new in Arduino, I want to connect my Sony Ericsson K810i with arduino Mega, I also follow the instruction from post http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1227581530/0, of course with different pinout of K810i that I found in DreamBox / Supported Phone Models

which is the TX is the DFMS and RX is DTMS, but it doesn't work..

Any idea how to correct it....Pls...Thank you
