It feels like just yesterday that we saw T-Mobile's original 4G Mobile HotSpot at CTIA (our review is here), and already the purgatory-presiding US carrier is ushering out a successor. Alongside the Galaxy S II and Amaze 4G, the Sonic 4G Mobile HotSpot is being revealed at Mobilize, and it's hailed as the carrier's fastest ever in the category. Predictably, it'll enable five WiFi devices to hop onto T-Mob's HSPA+ 42 network, and there's a microSD card slot for handling file transfers. The wow factor comes courtesy of the embedded OLED indicator display, which shows signal strength, number of devices connected, number of unread text messages, connectivity to the internet, battery level and network connection type. Lips are zipped on pricing, but it'll be available at your nearest Magenta retailer next month.
