C|Net’s Fourth Annual March Madness cellphone tournament is down to the Final Four this week, with the LG VX6000 vs. the Motorola MPx200, and the Treo 600 vs. the Motorola V600. We all know the fan-favorite Treo 600 is going to win, but we have to smile and pretend the other phones did a very good job. Then everyone gets a juicebox!
