Sony Ericsson T280 interfacing with 8051

Hi,
I have heard that T230 can be interfaced with 8051 by using serial communication through data cable. But the set is not available in market.T280 is available in market.I have never done interfacing of any mobile with 8051.

Now,I want to interface T280 with 8051 by using serial communication. is it possible or not. if, then how can be done interfacing.is there any difference between T230 interfacing with 8051.

Thanks
