Sony's unveiled its latest addition to its Xperia Z series, a new smartphone that blurs the line between smartphone and tablet once more -- the appropriately-named Xperia Z Ultra. Packing a 6.4-inch display that runs at 1080p resolution, it bests other similarlygigantic superphones that all currently hover around 720p. This new screen is paired with Qualcomm's latest and greatest mobile processor, the impressively potent 2.2GHz quad-core Snapdragon 800, throwing in 4G LTE connectivity too.
It all weighs in at 212 grams (over 50 grams more than the Xperia Z) but the body has been slimmed down to a mere 6.5mm uniform thickness, jostling with the barely-announced Ascend P6 for title of thinnest phone despite those high-end specifications (and screen dimensions). There's 16GB of built-in storage, 11GB of which is user-accessible, while a microSD slot will add an additional 64GB if needed. To power that screen, Sony has also cranked the battery pack up to 3,000mAh and we're hoping that will be enough for all those high-end components it'll be powering. There's no specifics on LTE bands just yet, but the phone also packs a pentaband HSPA radio, ensuring the global model will play nice on AT&T's 3G service, at least, when it launches later this year. We've got more details (especially on that display) after the break.
