An anonymous reader writes: Some owners of the new iPhone 5S say their phones came with an unwanted new feature more commonly found on Windows PCs in the 90s: "The Blue Screen of Death."
According to several discussion forums and videos posted online, the iPhone 5S unexpectedly reboots when you try to switch apps.
The problem appears to center on Apple's iWork suite. When someone has their 5S open to Numbers, Pages or Keynote and tries to go to a different app, a blue screen appears and the iPhone suddenly restarts.
