Apple has released today an exclusive update for iPhone 5 devices. The update, which brings the version number up to 6.1.4, is exclusively for the latest iPhone and contains rather minor changes. The update is available over-the-air and comes in at a rather small 11.5MB.
The update brings with it an "updated audio profile for speakerphone." Between both the size of the update and change log, we're convinced that this is an extremely minor update. Of course, updating to the latest version will break your jailbreak and we doubt an updated audio profile is enough to make you want to lose your jailbreak. For everyone else, you can grab the update OTA or by clicking your device version:
