Apple on Thursday released a minor software update for the iPhone 5 only. The change log for iOS 6.1.4 includes just one entry — “updated audio profile for speakerphone” — and it is unclear if the new iOS build includes any additional bug fixes or enhancements. IOS 6.1.4 is available from Apple immediately as an over the air (OTA) update, and it should also be available for download through iTunes shortly.
