RIM's last stand? The beleaguered BlackBerry maker will unveil five new smartphones Wednesday, including its first all-touch phone. The company, which basically invented the smartphone with the BlackBerry, has been struggling, falling to third place in North America behind Apple and Android and losing 68 percent of its share price over the past year. The new phones, however, won’t run on the company’s new operating system, QNX, which RIM bought last year. Phones using that system won’t be ready until next year.
