Bubble/Ricky-
Usually not without some fair work from the Admin (Programming.) iPhones (in particular), and most mobile devices march to the beat of their own drum. Most companies actually program a second website; or purchase a costly program, to create a standalone "m.348-409.com" type of address.
My advice; run with a traditional PC, or certain Android phones seem to like this website (and other websites) with less fuss. Sometimes it's Java/Flash, sometimes it's just the way they render.
