There is a slight irony about this: Apple’s latest iPhone, the 5S has an unexpected failure message: the Blue Screen Of Death (BSOD). An error typically seen on Windows computers, the BSOD would usually be followed by a restart, or unexpected restarts during device use.
So far, the trigger seems to be multitasking apps, and the current release of iOS 7.0.2 does nothing to fix the issue; instead it fixed the lock screen bug of days past.
In that case, it’s time for a quick bug fix, Cupertino.
