Some iPhone 4S owners have been experiencing a sporadic yet persistent issue that mutes all audio when a user places a call, and new reports claim that Apple's upcoming iOS 5 build will leave the problem unsolved.



From Apple Insider:

According to a 109-page thread on the Apple Support Communites forum, the problem cropped up when the iPhone 4S was launched in November 2011 only to remain unfixed when iOS 5.0.1 was released a month later to deal with battery life complaints, and a look at the new build of an update seeded to developers shows that the audio issues will likely remain unresolved, reports GigaOM.

The issue was first identified when a number of Apple Community forum members began to complain that the audio on their iPhone 4S was intermittently failing when placing calls, forcing them to hang up and dial again. Interestingly, recipients on the other end were unaffected and could reportedly hear the iPhone user who originated the call.
