Weve 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, its Sonys 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.
