AT&T today added a rare dual-mode 3G modem to its choices. Sierra Wireless' AirCard 890 at its core is an ExpressCard/34 modem that works in modern notebooks like the 17-inch MacBook Pro but has a special PC Card housing that will let it fit into older portables. It can reach up to 7.2Mbps downstream with either card format and has both GPS and VPN support for those that need them.
