Here's video from today's BlackBerry 10 North American launch event in downtown Toronto with Thorsten Heins of BlackBerry and Nadir Mohamed from Rogers Communications. The launch took place early morning in downtown Toronto with Heins and Nadir reminiscing about the long and history shared by BlackBerry and Rogers. Heins was asked why the BlackBerry Z10 wasn't rolling out to US carriers simultaneously and he stated that the delay is on the carrier side and that BlackBerry wanted a more comprehensive North American launch.
