Just as promised, the BlackBerry Z10 is now available for purchase from T-Mobile's website. The magenta carrier revealed last week that it'd begin selling the Z10 on March 26, but since then there's been no word on how much the new BlackBerry 10-powered handset will cost. That changes today, as we now know that T-Mobile is asking for a $99.99 down payment for the BlackBerry Z10, in addition to 24 monthly payments of $18 each. The full cost of the T-Mobile Z10 is set at $531.99.

As a quick reminder, the BlackBerry Z10 features a 4.2-inch 1280x768 touchscreen, 8-megapixel rear and 2-megapixel front cameras, 16GB built-in storage, microSD card slot, 2GB RAM and a 1.5GHz dual-core processor. The Z10 also includes support for T-Mobile's new 4G LTE network that'll be going live before the end of March, making it one of the first devices to support Magenta's new LTE service.

In addition to the Z10, T-Mobile is also launching a new 4G LTE-capable mobile hotspot, dubbed the Sonic 2.0 Mobile Hotspot LTE. Just like any other mobile hotspot, this device connects to the cellular network (in this case, either T-Mobile LTE, 4G HSPA+, 3G or EDGE) and then spits out that signal as a Wi-Fi connection that up to eight other devices can connect to. The Sonic 2.0 is powered by a 3,000mAh battery and features a 1.77-inch QVGA display that can show things like battery life, signal strength, the number of devices connected to it and how many unread messages a user has. Also included is a microSD card slot that can be used to share files with others that are connected to the Sonic 2.0's network. Expect the Sonic 2.0 to launch by the end of March for an undisclosed price.
