BlackBerry CEO Thorsten Heins confirmed this past May that BBM would come to iOS and Android “this summer”](BlackBerry To Launch BBM On Android And iOS This Summer | TechCrunch), which of course means that advertised launch window is rapidly closing. There’s still no official word on when BlackBerry is going to push its cross-platform messaging app out the door, some new images released today indicate things are chugging along at a decent clip.
