BlackBerry (NYSE:BB) shares have recovered nicely over the past month after falling off a cliff earlier this summer. As practically everyone knows by now, the company is officially shopping itself for a potential sale and has been doing so behind the scenes for more than a year. The problem is that there might not be anyone interested. The next-gen BB10 operating system isn't gaining the kind of traction the company will need to reclaim a meaningful place in the uber-competitive smartphone market, despite the launch of several sleek BB10 devices earlier this year. One of the most often-cited problems is BlackBerry's lack of pull with the developer community, which, as tech and telecom analyst Andrew Tonner explains in this video, might be worse than anyone realized.
