ORLANDO, Fla. (AP) — BlackBerry maker Research In Motion Ltd. unveiled a lower-cost BlackBerry that is designed to entice consumers in emerging markets as the company stepped up efforts to regain market share lost to the iPhone and Android devices.

CEO Thorsten Heins said Tuesday that the Q5 device will be available worldwide this summer. It is RIM’s third smartphone to run the new BlackBerry 10 system. The Q5 will have a physical keyboard, something that sets RIM’s devices apart from Apple’s iPhone and most Android phones.
