Sprint Nexus S 4G training

Dunno from whom or where this came, but it sure looks like someone's about to get all trained up on the Sprint Nexus S 4G. (See our hands-on at CTIA.) And it sure does look like it could see an April 18 launch. The Nexus S 4G, as you'll remember, is the same as the original Nexus S, with a Wimax radio thrown in for good measure. It'll cost you $199 on-contract whenever it does launch, and you'll have to shell out extra for the Wifi hotspot.

[Update: Got a tip that this is sort of a soft training launch from the rewards site that announces the trainings, and that we could see the consumer launch a week or two later. The source guesses on or about April 24.]
