Some newly surfaced rumors are calling for T-Mobile to release a relatively new Sony smartphone. That handset is the Sony Xperia Z and according to the details that have been shared up until now, the handset is currently in a testing period with T-Mobile. The key here, the handset is being tested and that bit alone means it may never show up for sale.
Basically, the folks at TmoNews are reporting they have 'confirmed' these details by way of three separate sources. Judging from the multiple source bit, it seems likely to believe this is actually happening. Needless to say, those sources have said the Xperia Z is being tested -- as opposed to released. Of course, assuming the testing period goes well and Sony and T-Mobile can agree on the fine print, a release then seems likely.
There was also some clarification that this is indeed the Zperia Z and not the Xperia ZL which recently came available for purchase here in the US. The US variant of the Xperia ZL is available unlocked and direct from Sony, however it does have support for the 1700MHz band which means T-Mobile LTE. Anyway, back to the Xperia Z.
This handset should arrive with a familiar set of specs. That is to say the Xperia Z will be running Jelly Bean with hardware to include a 5-inch (1920 x 1080) display, quad-core 1.5GHz Snapdragon processor, Adreno 320 GPU, 2 megapixel front-facing camera and 13 megapixel rear-facing camera. The Xperia Z is also water resistant for up to 30 minutes, a bit that was shown to us when we spent some hands-on time with the handset.
