AT&T recently met their goal of offering faster LTE wireless broadband service in 15 markets before the end of the year, and they're now pushing into additional markets. Several users who have bought dual-mode LTE-capable gear have written in to note that the AT&T LTE network last night popped up as available in portions of New York City, with users on the not-yet-open-for-business network reporting maximum downstream speeds topping out around 25 Mbps, and maximum upload speeds of 15 Mbps. As in other markets, the networks have come online ahead of any official announcement from AT&T -- so you can expect something official shortly.
