BlackBerry (BBRY) hasn’t yet announced launch details for its second BlackBerry 10 smartphone, the QWERTY-equipped BlackBerry Q10, but it still wants to make sure that developers are ready for the new phone once it becomes available. Apropos, the vendor on Tuesday announced a new “Dev Alpha C” developer handset that features a QWERTY keyboard and the same display dimensions as the upcoming BlackBerry Q10. The handset will allow developers to get acclimated with the BlackBerry 10/QWERTY combination and prep apps that work as well with the Q10 as they do on the BlackBerry Z10.
