Sprint's just-announced Tri-Network Hotspot, made by Sierra Wireless, will give you 4G data on its LTE or Wi-Max networks, depending on what's available where you are. If something goes awry, it'll fall back on 3G (EV-DO). Pricing and availability are still up in the air.
Ports and more
The hot spot handles up to eight Wi-Fi devices.
It also has 32GB storage.
Why is it so big and bulky? The 3,600mAh battery keeps it going longer, and is especially intended for frequent or prolonged use.
