Last month saw the AT&T, T-Mobile and Verizon versions of the Moto X sink their teeth into Google's KitKat bar, and today Motorola has revealed the next Moto X variant that's getting a bump up to Android 4.4. Motorola's Punit Soni today announced that the U.S. Cellular Moto X is receiving its update to Android 4.4 starting today, Dec. 4. The update brings USCC's Moto X up to software version 143.44.2.ghost_usc.USC.en.US and includes the following goodies:

• Android™ 4.4, KitKat®: Android 4.4, KitKat, is the latest release of the Android platform. KitKat includes enhancements such as restyled status and navigation bars, a new full-screen mode, color emoji support, improved closed captioning support, stronger security, smarter power use, and more tools and capabilities for better app development.
• Phone dialer: Improved the phone app with the ability to look up contacts directly from the dial pad, see and tap frequent contacts, and search your corporate directory easily.
• Camera - Focus and exposure: Enhanced the "touch to focus" option with a new circular, on screen control that can be dragged by your finger around the viewfinder to adjust a photo's focus and exposure.
• Gallery - Photo editing: Added new photo editing options to the Gallery app including new filter effects, draw on your photos, advanced cropping, and adjustments to color, exposure, contrast and more.
• Hangouts -SMS/MMS support: Incorporated a new version of Google Hangouts that supports integrated SMS/MMS messaging. Hangouts can be set as the default SMS app under Settings > Wireless > Default SMS app.
• Touchless Control - "Find my phone": Added a new "Find my phone" command to Touchless Control. Just say "OK, Google Now-find my phone" and your Moto X will ring loudly to let you know where it's hiding when you've misplaced it nearby.
• NFC - Host card emulation: Enhanced support for NFC Host Card Emulation (HCE), to improve experiences such as contactless payments, loyalty plans, transit passes, card access and more.
• Accessory support: Added support for Square credit card reader

Soni does note that the U.S. Cellular Moto X's KitKat update is going out in phases, so it may take some time before it makes its way to all users. Those of you that have a Moto X in your pocket that's still on Android 4.3 can pull that sucker out and check for the update manually by going into Settings > About phone > System updates.

In other Moto X Android 4.4 news, Republic Wireless has offered up a timeframe in which its own Moto X is expected to be treated to some KitKat goodness. Republic revealed today that its Moto X should receive a bump up to Android 4.4 in early 2014. Obviously that's a somewhat vague window of time, but hey, at least Republic Moto X-ers don't have to stress themselves out over the holidays by wondering where their taste of KitKat is at.
