There are still great swatches of the American wireless industry woefully lacking in LTE coverage (we're looking at you, T-Mobile) but bit by bit the various carriers have been hopping on the bandwagon. While budget carrier Cricket Wireless has actually had LTE coverage in Las Vegas and Tucson for the last few months, it'd been restricted to USB access dongles, WiFi hotspots and the like. Their first LTE smartphone, the LG Optimus Regard. Yup, that's the name they went with.
The Regard fits neatly into the low end, with a 3.5-inch screen running at 480x320. At least its' got Android 4.0, though it's also running LG's custom skin.
