AT&T this morning added just its second Sierra Wireless device in recent memory with a new USB 3G modem. The USBConnect Lightning (shown soon) supports the carrier's faster 7.2Mbps HSPA network where it's active and is also slightly more advanced than most with a hinge design to fit oddly-shaped notebooks and a lit-up faceplate. It continues to support regular 3.6Mbps HSPA as well as legacy GPRS and EDGE.
