T-Mobile's UnCarrier announcement event is taking place a little later today, but some bits of news have started to leak out ahead of time. First was the BlackBerry Z10, and now comes an LTE mobile hotspot, the Sonic 2.0. It's T-mo's first LTE mifi and can feed data to up to eight devices at a time. Not only that, it's compatible with both Mac OSX 10.8 and Windows 8, plus Microsofties get the added benefit of compatibility with the Win8 Carrier application so users can easily access real-time data usage info for every connected gadget. As for the hardware, the Sonic 2.0 has a 1.77-inch color LCD on the front, a 3,000 mAh battery, 802.11 b/g/n WiFi and quadband LTE and 3G radios on board. There's also a MicroSD card slot for simple file sharing of up to 32GB cards. It'll be available by the end of the month, though we don't yet know how much it'll cost. Guess you'll have to tune into our liveblog to find out.
