No software is without bugs and Apple is no longer the exception. It has become common, similar to other major software releases, to advise users to hold off for a week or two before updating to the latest iOS version. Of course, that didn't stop eager beavers, some of whom may have paid the price in the form of some annoying crackling sound coming from the phone ear speakers. Never fear, because the software fix is finally here. And, yes, this is the one time you might want to immediately download and install that update.
