Welp, that didn't take long. Just weeks after US Cellular's first LTE device hit the shops (yeah, the Galaxy Tab 10.1), in flies the carrier's first 4G LTE smartphone. It's the Samsung Galaxy S Aviator -- otherwise known as the Droid Charge -- taking the crown, shipping today with a 4.3-inch Super AMOLED Plus touchpanel, front-facing camera, Android 2.3.6 (Gingerbread), an eight-megapixel rear-facing camera, an HDMI output and access to Google Play (despite the deceased 'Market' logo shown on the press imagery above). The bulk of you will be asked to pony up $199.99 on a two-year contract (and after a $100 mail-in rebate), but "select" LTE cities will be selling it for $100 less; as for LTE service, we're told that portions of Iowa, Maine, North Carolina, Oklahoma, Texas and Wisconsin are being served now, while coverage is expected to expand to Illinois, Maryland, Missouri, New Hampshire, Oregon, Tennessee, Vermont, Virginia, Washington and West Virginia in the latter half of the year.

There's a first for everything, including Engadget stories about software updates for thermostats. If we're going to suddenly start getting granular in our coverage of home automation products, though, we may as well start with the Nest, a device slick enough to make us use "thermostat" and "sexy' in the same sentence. Now that it's been out on the market for about five months, the company's issuing a software update that introduces a couple new features.

For starters, particularly fastidious users can now access a detailed 10-day history, showing precisely when and for how long their heating and cooling systems kicked in, as well as the reason for that shift (e.g., you manually changed the temperature, were away). Though you can't view all that data on the device's small, circular screen, you can look it up online or through Nest's iOS and Android apps. Next up is Airwave, a feature that uses your fan to distribute chilled air through the home after your air conditioner has turned off (you know, instead of letting one room get intensely, unnecessarily cold). According to Nest, that feature turns on automatically when the temperature is high and the humidity low, though we're hazy on the algorithm being used there. Rounding out the list, Nest has made certain settings easier to access, and the hardware itself will ship with redesigned connectors that purport to work well even without wall anchors. Save for that last bit, current owners can enjoy all these tweaks via a free software update -- fully automated, 'o course.
