The D-Link MyPocket DIR-457U is a combo 3G USB modem (3.75G) and WiFi router squeezed into a smooth white plastic shell roughly the size of an iPhone. Most people refer to it as a "MiFi" device, after the first such commercial model made available in the US market last year.

The D-Link MyPocket is a 3G wireless router the size of a smartphone. Sliding off the back cover, you find a SIM card slot, a microSD card slot and a rechargeable lithium-ion battery that lasts for a couple of hours when using 3G, and for just over four when used simply as a wireless router.
