We first heard of Application Resource Monitor back in May of this year and it was a novel concept for RIM. The app would shut down offending and battery consuming apps before they could cause major harm. The only catch was that the app only shipped on OS versions after a certain date which many carriers have not updated to officially. That means users have been left without Application Resource Monitor.
Earlier this month RIM released Application Resource Monitor in the Beta Zone for all OS 7.1+ devices and now Debbie let us know it has been rolled out to App World. That means you can go an pick up Application Resource Monitor free in App World at this link.
