No, and I don't really see any reason to connect the phone to TV, since it don't have an HDMI output, and it can't play DiVX videos.
Still, you can connect your phone to your sound system by a jack-jack cable, and the sound system's AUX plug. I'm using a 5.1 audio system like this, and it is great to listen to my music like this. You should give it a shot.
