We've seen many a tablet turn into a road warrior -- or even a huge phone -- with the addition of a SIM card. A phone becoming a tablet is a much scarcer transformation, but if any device can make that switch, it's Sony's nearly iPad Mini-sized 6.44-inch, 1080p Xperia Z Ultra handset. A variation of that model (the SGP412) has appeared at the FCC packing a Snapdragon 800 MSM8074 SoC processor sans mobile baseband radio, normally used in WiFi-only tablet variants. New application photos of a half-submerged test model show it to be just as dunkable as before, while still packing 2GB of RAM, 32GB of memory, a microSD slot, 3,000mAh battery and an 8-megapixel camera. There's no official word about the device, let alone pricing and a launch date, but when it does come it'll likely need to beat the Mini's $399 sticker -- nearly half the Xperia Z Ultra's off-contract price.
