Verizon has yet to go live with its 4G network in even a single market, but regional carrier MetroPCS is now on its third -- and yes, it's still the only company in the country with any commercial LTE presence whatsoever. Having already taken Vegas and Dallas to the promised land, Detroit is the latest city to sup on the sweet, sweet nectar that only a next-generation network can provide; unfortunately, MetroPCS has yet to deliver any smartphones or modems capable of taking advantage of it, but that's another story for another time. For now, the only device available is the Samsung Craft, a dumbphone with a heart of gold that offers a landscape QWERTY keyboard and access to MetroPCS' 4G-friendly video on demand service for an extra $5 a month. We'd love to see a mobile hotspot or two, of course -- but seeing how young the network is, we imagine these guys would still like to start out slow with the Craft and work their way up to the big guns.
