As the CNET cell phone tournament finishes its fourth year, here's a look at the winners, all of which are legends in their own time. In 2001 and 2003, we saw two underdogs walk away with the crown, while 2002's champion, the Sony Ericsson T68, was among the pretournament favorites. This year's victor, the Treo 600, was a favorite from the onset.

For those who missed the earlier games, here's the deal: We don't have 64 phones (there just aren't that many good ones on the market), but we've chosen 16 top models to do battle in a single-elimination tournament that more or less follows the schedule of the real NCAA competition.

The rules
Like any good game, our contest has guidelines to ensure fair play.

The hall of fame
We take a look at all the winners, all of which are legends in their own time.
