It looks like Samsung and Sprint are almost ready with the Instinct successor. It is smaller than the original Instinct and was christened as Instinct Mini but if we go by the new info, it will be known just as S30. The features are still unconfirmed but we can expect it to have the new 3D TouchWiz UI, an upped camera and host of other features carried over from its predecessor. Engadget pins for the April release date since it coincides with CTIA.
