The Sony Xperia Z1S, T-Mobile’s Xperia Z1, was one of the phones announced at this year’s CES in Las Vegas. It is basically your typical Xperia Z1, with some added carrier-specific bits, and an aluminum frame that has now been removed and replaced by a plastic one, while still maintaining the sandwiched glass build. It is now available on T-Mobile for a full retail price of $528, which translates to 24 installments of $22, plus your service fee on top of it, with $0 upfront.
The Sony Xperia Z1 Compact was the other Las Vegas phone, basically the flagship Z1 — with some changes — packed in a smaller, pocket-friendly form factor. While it is not yet officially available, the phone has already received its root treatment thanks to the community. There’s also a CyanogenMod-based recovery available so if you’re planning on grabbing the device once it will become available, bookmark the XDA thread in the source link below for downloads, instructions, and feedback.
