Update: Motorola is saying that the OTA was delayed slightly. It should start rolling out today 2/13.
Right on the heels of the T-Mobile update, US Cellular's Moto X is getting the bump up to version 4.4.2. This OTA started hitting a few devices last week, but now it should be rolling out to everyone. Head to the settings and check your update menu at your earliest convenience.

There was an unusually specific leak from Samsung last month, showing a relatively accelerated schedule for updates on the Galaxy S4, S III, and Note II on all four major American carriers. That isn't much comfort for those customers on US Cellular, since the #5 carrier wasn't quite important enough to be included in the leak. But now there's a new leak in town, helpfully provided by an anonymous tipster, showing that the US Cellular Galaxy S4 will be updated on Friday the 8th.
