Before wrapping things up at the BlackBerry 10 Jam keynote, Alex Saunders lobbed out a whale of a tidbit: the Dev Alpha may be joined by another, "very limited-edition" version of a BlackBerry 10 device much closer to the platform's official launch. According to the VP, developers who have received the Dev Alpha will be able to trade up to the new version at an unspecified time. With Alex accentuating the fact that there would be an incredibly limited number of these devices available, we imagine we'll see some extra strings attached to this offering, but no specifics have been revealed so far.
