The Wall Street Journal is reporting that a Samsung has executive publicly stated that U.S. pre-paid wireless provider MetroPCS will launch its new 4G LTE-based network next month. Jaebeom Choi, vice president of systems research and development for Samsung, quipped that MetroPCS will light-up their LTE network in Las Vegas and Dallas sometime in September. The company’s first LTE device will be the Samsung Craft, which we reported on earlier this month. If the VP’s statements are accurate, the company — which is currently the fifth largest wireless provider in the U.S. — will be the first Stateside wireless carrier to offer LTE services publicly. When contacted, MetroPCS declined to comment on the report. Now all the company needs is a better marketing campaign to promote their new service.
