Captivate Keep Alive A new, free app in the Market that claims the following: "Prevents the Samsung Captivate from randomly turning off when fully charged. This app prevents the CPU from sleeping while the battery is above a threshold you set - which stops the random shutdowns." I have no idea about its usefulness, but thought I'd alert those suffering from random shutdowns about its availability. Will this app avoid having to exchange phones - or is it snake oil? Feedback would be helpful for others similarly affected.
