It turns out BlackBerry users don’t love what the smartphone makers do. The manufacturer of BlackBerry phones, Research In Motion, saw its stock nosedive Friday as RIM shares tumbled 20 percent. Investors Friday tried to dump their shares after a dismal quarterly report had some wondering if the company will need to be sold, broken up, or whether it needs new leadership. The sell-off cost RIM $3 billion in market capitalization, and it proved how hard times had come for the company that was once the largest seller of smartphones. This year RIM tried desperately to compete with Apple’s iPad by creating a tablet computer, but the results—a tablet called the Playbook—were disappointing and many worry the company is falling too far behind Apple and Google.
