It works well, if you login to the site on your phone you get the full site by default. scroll to the bottom left in the footer and hit the drop down that says "Phandroid Skin"
choose "AF Mobile" that will switch it to mobile site. and it should remember it VIA cookies for subsequent visits.
few things if I may
add a "standard site/skin" link to the bottom of the mobile skin so we can switch back if we want
remove the top 5 stats box from the mobile skin
add a little logo/header image to the mobile skin
