While it’s obviously way too soon to tell whether users will like RIM’s (RIMM) BlackBerry 10 operating system, one RIM executive says that wireless carriers are already big fans. AllThingsD reports that RIM managing director of Canadian operations Andrew McLeod told reporters at a press briefing Thursday that there has been a “tremendous” response to BlackBerry 10 from Canadian carriers, and he described some carrier executives as “visibly positive and visibly enthusiastic” about the new operating system. McLeod went on to say that RIM is “in the process of finalizing the software” and that the company now has enough confidence in the product to start showing it off more.
