This morning, I lost service on my iPhone. No Safari, no texts, no Google Maps, no App Store, etc. A message appeared saying something about no server. In a panic, I shut it down. Is that what is called re-boot? I powered-up and miraculously, the server was up and running. What happened? Why did I lose all service? As a new user, I was scared to death. Does this happen often? This never happened with my old Razr phone; I never lost all service.
