I am legend!

Warner Bros. is creating a campaign for I Am Legend that uses some of today's hottest gadgets and software.

The studio launched a site for the upcoming Will Smith movie specifically for iPhone users. The special site replicates much of the full official site, including iPhone-formatted trailers and wallpapers.

There's also a "daylight meter" widget that shows the hours of daylight left.

In the movie, Smith's character must retreat to safety at night to avoid the ghoulish, mutated survivors of an apocalyptic virus.

Warner Bros. is also promoting I Am Legend in Second Life with the "I Am Legend Second Life Survival" game. Residents of the virtual world can play an uninfected human or a Darkseeker, the villains of the film.

Gamers are tasked with finding a cure for the virus that wiped out much of humanity.
