Alternate Uniforms on Madden 07 /360

I know you're supposed to be able to download 'em but when i log on to xbox live marketplace, all they have is a bunch of themes and gamer pictures... Also, is there a way to download updated rosters that I don't know about?

for PC -
Football-Freaks -> Downloads (Madden PC, NFL Head Coach PC, NFL News & Football Forums) (http://football-freaks.com/forums/index.php?act=Downloads)

updated rosters, hacks, editors, etc etc

for xbox 360 - no clue, sorry :(
