Sony’s got a new flagship super-phone: the Sony Xperia Z1s for T-Mobile. Like the Xperia Z before it, the Z1 is waterproof and can take pictures fully submersed in water (including with Flash). Under water, the 1080p Triluminous display uses tracking technology to register fingers’ presence. The camera’s 20.7-MP sensor, f2.0 G lens, and cool cam software like TimeShift Burst that captures 61 shots in 2 seconds means you’ll want to take as many pictures as possible. Look for the Z1 for free from T-Mobile on January 22 and $22 month after purchase.
