Recently I installed the latest upgrade OS and I am getting random reboots. Has happened with Safari, words with friends and other assorted apps. Kind of a pain as sometimes the app I was running loses the last entry and reverts to a previous entry. Previous update seemed to solve the problem that a earlier version had problems with the random reboot. Now the new OS (7.1.2) has the same problems as IOS 5. Anybody have a clue?
