T-Mobile has posted the changelog for an over-the-air update now rolling out to Xperia Z1s owners. The primary new feature is the inclusion of in-flight texting support. This way users can communicate with folks on the ground for free via Gogo thanks to a partnership T-Mobile debuted a couple months back.

Sony tends not to push its flagship phones on US carriers, for whatever reason. Sometimes a tweaked version will happen along at a later date, and that was the case with the Xperia Z1.
