T-Mobile may have passed on carrying Sonys Xperia Z1, but we now know thats because it wanted to offer something ever-so-slightly better: meet the Xperia Z1S. The Android 4.3 handset shares the Z1s 5-inch 1080p screen, 20.7-megapixel camera, Snapdragon 800 processor and waterproofing, but it includes a raft of hardware and software tweaks. Theres now 32GB of expandable storage, a Background Defocus camera mode and a headphone jack that can stay exposed while underwater.
