We've already gotten a couple of strong hints that the Sony Xperia Z will soon be available on T-Mobile, but for anyone out there that may still be a tad skeptical, I've got another piece of evidence that may seal the deal. As you can see in the screenshot above, searching for "Xperia Z" on T-Mobile's website yields a large list of support documents for the device. Unfortunately, all of the docs appear to be placed behind a login, so we're not able to actually view any of them at this time.
Along with these support documents, we've recently been treated to peeks at a T-Mobile-branded version of the Xperia Z both in the wild and in the FCC. Neither Sony nor T-Mobile have said anything official about an Xperia Z release, but Sony CEO Kaz Hirai did tease last week that his company is planning to partner with a carrier to make an announcement related to that device "soon." With today's appearance of these support docs, it appears that nearly all of the pieces for a T-Mobile Xperia Z launch are in place. Now we just have to sit and wait for that aforementioned announcement that Hirai alluded to.
