Some history relating to Cisco and T-mobile for those interested:

Cisco acquired linksys in March of 2003 - right around the time that T-mobile and Calypso were developing / testing / demonstrating the ASNAP technology on the T-mobile network using linksys routers.

Calypso demonstrated the ASNAP technology in March of 2006 at the VON spring conference in California.

T-mobile comes to market with HotSpot@Home without Calypso patented technology in June of 2007 offering both D-Link and Linksys routers.

T-mobile disscontinues the hotspot@home service in January of 2010 after being put on notice by Calypso:

So after looking at the technical history between these companies, you have to come to the conclusion that since Cisco owned Linksys during the trials with Calypso and T-mobile in 2005 and 2006, that they are also on the hook for infringment for the hotspot@home solution. They have also clearly been developing and implementing this technology into their products for the past several years.
