We got a taste of AT&T's 4G LTE action last night in the Big Apple with the introduction of its LG Nitro HD, and today, the company has apparently flipped the 4G "on" switch in the City That Never Sleeps -- confirming its promise from November. According to tipster reports, some speed tests are showing downloads as fast as 27 Mbps and uploads of 15 Mbps, confirming that the LTE network has indeed gone live in parts of New York City.
Update: To be clear, this is not an official deployment of LTE in NYC by AT&T. So, if you can't get signal, or if your signal stinks, don't take it out on them. It's still in testing!
