TmoNews is reporting that the Sony Xperia Z (C660X) is being tested on T-Mobile’s network in the US. We imagine it would be a new C6606 SKU that would make an appearance, bringing support for North American LTE bands much like the Xperia ZL (C6506) which supports LTE Bands 1, 2, 4, 5 and 17. The important one here is Band 4 which supports T-Mobile’s LTE network. The C6606 SKU has been spotted before of course, such as this PlayStation Mobile listing, so we’re sure it is in the wild, even if only on a prototype level.
TmoNews has also revealed a leaked picture of the Xperia Z with T-Mobile branding on the back glass. Apparently they confirmed with three separate sources that the phone is being tested with T-Mobile. Despite this, there’s no guarantee that the phone will see a launch. Time will tell if anything more comes of this, we’ll keep you posted.
