After all, T-Mobile being one of the so-called “Big Four” mobile carriers in the US, ought to carry this flagship waterproof and dustproof device from Sony. We have already given the Sony Xperia Z1 a rather lengthy review just recently, so you might want to check out that particular review of ours before you make a decision as to whether to bring the Xperia Z1 under your fold of smartphones or not. At this point in time, it remains to be seen just when will T-Mobile make an official announcement concerning the exact date as to when the Sony Xperia Z1 will be made available, and neither do we have an inkling of the price detail. Sooner would be better than later, of course, so hopefully the folks at T-Mobile will not disappoint.
