three-day exclusivity in advance of the Sensation 4G's "official" June 15th arrival at T-Mobile? Apparently the head start wasn't sufficient for Wally World, as many associates are now passing this hot little number across the counter without batting an eye. While some employees appear to have gotten the June 12th memo, the point is moot because Walmart's point-of-sale computers are more than willing to process the sales. So, if you're able to track down an unknowing (or empowered) sales clerk, those HSPA+ dreams might come true sooner than expected -- for the low price of $148.88. Now, who's up for some Walmart Bingo?
