One of our trusty Walmart ninjas just sent word and some quick pics of the Galaxy S 4G arriving in stores. While they aren’t supposed to sell the device till the 23rd, surely you could persuade an unknowing rep to part ways with it. Of course we can’t give our blessing for that, but it wouldn’t be the first time Walmart has let a T-Mobile device sell a little early. If you’re interested in scoring a Galaxy S 4G from Walmart earlier or on launch day, it’ll set you back $148.88.
