Macworld.com – The fervor over March Madness is akin to the excitement over the Olympics: even if you’re not a typical sports fan, you can’t help but be interested.  Me, Iâll watch maybe one college basketball game during the regular season, but come tournament time I can’t help but refresh scores and update my bracket like any other diehard. This year, two versions of CBS Sports Mobile’s March Madness iPhone app should make that easier than ever.
