Apple has released a minor update for iPhone 5 users, versioned as iOS 6.1.4 with a build ID of 10B350. The brief release notes suggest the only change is an "Updated audio profile for speakerphone", though in our own before and after testing we were not able to determine any obvious differences in speakerphone output sound or quality upon installing the update.
Update to iOS 6.1.4 through OTA
The new version is quite small at 11.5MB when downloaded as an over-the-air delta update. OTA is the easiest way to install the update and can be done by doing the following:
- Open Settings, go to "General", then "Software Update" and choose "Download and Install"
To use OTA update you must be connected to a Wi-Fi network. Even though the release is quite small, it's always a good idea to backup before beginning in the odd event that something goes wrong.

Most users should use the automatic updates through OTA or iTunes, but if you're going the IPSW route be sure to download the proper version for your device. iPhone GSM models relay on a SIM card, while CDMA models do not, if you have no idea which your device is you can learn how to determine which version you have by clicking here.
As of now, the update is available exclusively for iPhone 5 users, though it's possible that Apple will issue a delayed rollout for other devices as well.
