Revenge of the Blackjack

It looks like Sprint and Samsung have been working together to bring a portrait QWERTY Android phone, and have at least got to the prototype stage.  Not much information about this one is known, but Pocketnow got their hands on a few photos that shows a Droid Pro-esque phone, and it's clearly (as clear as blurrycam can ever be) running Android.  

Could this be part of Sprint's Magical event next week, or something we'll see at Mobile World Congress?  Or is this just a one-off for now?  And maybe most importantly, will it be called the BlackJack S?  We'll keep you posted as we know more.  [PocketNow]
