NEW YORK (AP) — Shares of Blackberry maker Research in Motion slumped more than 16 percent Friday with future revenue coming into question and a declining number of subscribers.
RIM's stock jumped initially Thursday when the Canadian company released better-than-expected third-quarter results and a stronger cash position.
Shares reversed course during a conference call later, when executives said that the company won't generate as much revenue from telecommunications carriers once it releases the new BlackBerry 10.
