Question about using Mobile AIM on a RAZR V3c

So I've got AIM on my RAZR, and think using the Moviefone IM bot would be really handy. But I can't seem to get it to work. I've added Moviefone to my friends list, then to my 'Mobile Device' group and it won't even show up my buddy list. When I send an IM to Moviefone directly it goes through, but I get no response. Anyone have any ideas on how to get it to work? Or is it not even compatible with the phone?

Any help would be greatly appreciated!
