MSN Contacts not showing up on Yahoo Mobile?!?!?!?

I added my msn messenger contacts to my yahoo im. When I am on the computer it works great and I can chat with my msn contacts through yahoo. But when I use Yahoo mobile my msn contacts do not appear on my contact list. Is there anything I can do to fix this?? Please help me asap.

"The federation between the Yahoo and Windows Live IM clients are handled within their respective clients. I doubt we'll see this federation carry over to mobile clients, with the exception of WLM for Windows Mobile (if then).

On a side note, if your corporation is on BES 4.1+ and has an Live Communications Server/Office Communications Servers (LCS/OCS) deployment with Office Communicator and Public IM Connectivity (PIC) enabled with federation to the IM clouds, then you can chat with contacts on AIM, Yahoo, MSN and internally (Office Communicator) from Enterprise Messenger."

Hope that made sense, found it on a site.
In other words, there is no way to fix it, as far as I know.
