Cisco does support the AnyConnect VPN for mobile devices according to their VPN compatibility reference guide “SSL VPN Clientless - You can access Clientless SSL VPN from your Pocket PC or other certified personal digital assistant (PDA). Neither the ASA administrator nor the Clientless SSL VPN user need do anything special to use Clientless SSL VPN with a certified mobile device.”

While they list that you do not need to do anything special to use the Clientless SSL VPN it does have to be setup on the firewall device to work. This is something I will be trying after the first of the year.
