A few lucky T-Mobile owners of the Moto X will be seeing the newest version of Android. The soak test for Android 4.4.2 is supposedly rolling out to testers. This new build isn't a huge update over the previous 4.4 version of Android, but it does bring a few goodies along for the ride, (like an improved camera). This test build is version 161.44.25. If it is successful we should see it start to rollout to everyone else in the coming weeks. We will keep you updated as more info arrives.
Now if we could just get a soak test for the other three carriers...
