Could this be a new Virgin Mobile device?

Virgin Mobile IS Sprint. Both Boost and Virgin are running off the existing Sprint iDen and CDMA towers.
 
You cant put an Evo on Virgin or an Optimus V on Sprint, so the two shouldn't be considered to be the same entity. Virgin Mobile is an MVNO of Sprint.
