Don't ya just love it when a plan comes together? As expected, T-Mobile has confirmed that its 4G Mobile Hotspot will be hitting stores tomorrow. The ZTE-sourced sliver of plastic and OLED will be T-Mo's first such device and, with its HSPA+ radio, clocks in at 21Mbps, while an SD card slot means it can provide up to 32GB of wireless storage. You can read more about it from our hands-on, or just go get your own tomorrow for $79.99 -- after the requisite rebate and contract negotiations, of course.
