Apple has, unexpectedly, released a new version of iOS this morning. The update brings the firmware to 6.1.4, and doesn’t appear to include any new features or changes other than an ‘updated audio profile.’
The update is currently only available via OTA (over the air update), but it should be on iTunes.
Jailbreakers stay away from this update and from iOS 6.1.3 update. You will lose your jailbreak, and iOS 6.1.3 and 6.1.4 aren’t jailbreakable.
Maybe behind the description of the update are changes as well. If you don’t have jailbreak and you don’t want jailbreak you can install this update.
If you installed the update, tell us how it works!
