It's a big day for Samsung, which is unveiling the Galaxy S4 in New York City later today. But leave it to LG to preemptively let a little air out of that balloon—with this gloating billboard in Times Square, designed just like the Samsung one below it. "Be ready 4 the next Galaxy"? Well, the "LG Optimus G is here 4 you now." Bickering billboards, of course, are a time-honored tradition, from Newcastle's takedown of Stella Artois to the famous BMW/Audi spat out west. Via CNet.
