It was only a couple of weeks ago that we got an early peek of T-Mobile's Xperia Zthanks to the FCC, but we've now already gotten word of another unannounced Sony handset. While the published FCC report doesn't offer much more than a label, Blog of Mobile has turned up some images of what's purported to be the Xperia UL (codenamed "Gaga"), giving us an early look at the 5-inch device clearly inspired by other members of the family design-wise. What's more, the UL is allegedly sportingQualcomm's Snapdragon 600 chip, along with 2GB of RAM, 32GB of built-in storage, a 2,300mAh battery and waterproof / dustproof attributes (these being common Japanese standards). Word on the internet is the Xperia UL will be launching as aKDDI exclusive, though we'll have to wait for something more concrete to see if that's indeed the case. Until then, you can peruse the gallery after the break to get a slight idea of what to expect.
