Sony tends not to push its flagship phones on US carriers, for whatever reason. Sometimes a tweaked version will happen along at a later date, and that was the case with the Xperia Z1. T-Mobile got the Xperia Z1s in January of this year, but it was still on Android 4.3. Well, not anymore—KitKat is rolling out now.
Fitbit's Android app is useless without a matching fitness device to pair it with, but buying one without having a phone that supports it means having to rely on your computer for synching. That's less than desirable, so it's a good thing that the company is steadily working to expand the number of Android phones its products will support. Following the latest update to the Fitbit app, Moto G owners can now sync their handset up to a Fitbit accessory.
The new Xperia Z1s on T-Mobile is almost identical to the international Z1, except for the radio bands and some software tweaks. One thing that definitely isn't the same is the bootloader – it appears that T-Mobile has requested Sony not allow bootloader unlocks on this device. For a company trying to upend the traditional carrier model, this is awfully old-fashioned carrier behavior.
Sony has two new phones to announce here at CES in Las Vegas: one specifically for the purple people over at T-Mobile, and one meant to appease users who want a premium phone without the bulk. The Xperia Z1s is T-Mobile's branded variant of the slightly older Xperia Z1. Aside from the extra letter and doubled storage, it's identical to Sony's international flagship. The Xperia Z1 Compact is a smaller 4.3" phone that keeps most of the premium features.
Update: It looks like some signals got crossed. This is the Sony Xperia Z1 Compact - the "Z1s" is a T-Mobile branded variant of the original 5-inch phone.
It's been said that those who want a powerful modern smartphone with a non-gigantic screen don't have a lot of options. If a new post from the tireless Evleaks is to be believed, they'll have at least one more on T-Mobile very soon.
