TORONTO (AP) -- Research In Motion's stock plunged in after-hours trading Thursday after the BlackBerry maker said it plans to change the way it charges fees.
RIM also announced that it lost subscribers for the first time in the latest quarter, as the global number of BlackBerry users dipped to 79 million.
In a rare positive sign, the Canadian company added to its cash position during the quarter as it prepared to launch new smartphones on Jan. 30. The new devices are deemed critical to the company's survival.
RIM's stock initially jumped more than 8 percent in after-hours trading on that news, but then fell $1.48, or 10.4 percent, to $12.65 after RIM said on a conference call that it won't generate as much revenue from telecommunications carriers once it releases the new BlackBerry 10 platform.
RIM is changing the way it
