The Sony Xperia Z1S, which was announced just last week at CES in Las Vegas, is now available on T-Mobile in the United States. Customers will pay either $528 for the device up-front, or 24 monthly payments of $22.

The Xperia Z1S is essentially the same smartphone as the Xperia Z1; it has the same 5-inch display with a 1080p resolution, the same quad-core Snapdragon 800 chip, and the same 20.3-megapixel rear-facing camera. It also runs Android 4.3 Jelly Bean.

So, what’s the difference? Well, unlike the original Xperia Z1, the Xperia Z1S is compatible with T-Mobile’s LTE bands, so you’ll get super speedy data in areas where it’s available.

What’s more, Sony is offering customers who pick up the Xperia Z1S and a PlayStation 4 between January 13 and January 21 a free Visa gift card worth $100. Simply keep your receipts for both devices and mail them to Sony, and they’ll send your gift card back to you.
