Every hour I hear a high pitched squeal coming from my iphone 4s running ios 6, it lasts about 2 seconds and is really annoying.


I have tried a reset but every hour, on the hour it happens again, all day, all night.


It's as if it's doing some kind of check every hour but doesn't play a beep, just this very high pitched sound. I've seen others with the same problem but there has been no solution to this.


Anyone have any ideas on what could be causing this?

iPhone 4S, iOS 6
