It's been a hot minute since the folks at T-Mobile have introduced a new USB WWAN modem, but if the document above is to be believed, that could be changing in short order. As the Jet ages, it looks like a few others -- codenamed Kitty Hawk, Washington and Wayne -- could be swooping in to take things from here. The former is rumored to hit shelves in March, offering HSPA+ speeds of 21Mbps and the ability to solve most of the world's problems. As for Washington? That'll be T-Mob's first USB modem to offer HSPA+ speeds approaching 42Mbps, and if all goes well, this guy will also splash down next month. Moving on, there's a pair of Waynes that'll serve as the carrier's first mobile hotspots, enabling five WiFi-enabled devices to mooch off of a 21Mbps (Lil' Wayne) or 42Mbps (Big Wayne) connection. Here's hoping T-Mobile does the smart thing and sticks with the codenames -- the marketing exec in us just knows it's the right thing to do.
