It's possible to configure nginx with the map directive [1] with the
$http_user_agent embedded variable [2], something like this (not tested):

map "$http_user_agent" $mobile {
    default      0;
    "~*ipod"     1;
    # define other user agents here
}

server {
    ...
    if ($mobile) {
        return 301 http://m.yoursite.com.br;
    }
}

Hope that helps.
