As New York City crews are busy clearing feet of snow from Times Square in anticipation of Friday night's New Year's Eve celebration, AT&T is doing its part to help ready the "center of the universe" by expanding its WiFi coverage to better accommodate an expected 1 million guests.

AT&T debuted its Times Square WiFi coverage in May, but it was limited to specific and small areas of the square. Now, the coverage will be expanded to supplement AT&T's 3G signals to help users in the most crowded area of the city quickly post photos and messages and communicate with friends. And, since using a WiFi connection requires less battery power than a 3G connection, people will be able to stay connected longer without fear of a dead battery.

Smartphone users heading to the biggest party in the country, remember: a 3G signal is still required to make phone calls or receive text messages (unless you're using Google Voice), so plan accordingly!
