iOS 6.1.4 Released For iPhone 5
During this evening Apple released iOS 6.1.4 only for the iPhone 5 terminal, the new version of the operating system bringing a new profile for the device speakers. iOS 6.1.4 is not available for other devices and outside the new profile does not seem to bring other changes, its size is of only 11.5 MB in OTA version. Apple said it will release iOS 6.1.4 to implement some changes in VPN system, but seems to be limited only to a minor update.
To install iOS 6.1.4 on your iPhone you can access either the Settings menu>General>Software Update to perform OTA Update directly from the terminal, if you do not jailbreak, you can download the ipsw file using the link below and you can use it in iTunes to perform a restore.

If you did a jailbreak on iPhone 5 and you want to keep it, then the answer is simple: do not install iOS 6.1.3 or iOS 6.1.4. Doing this means deleting the jailbreak and changes implemented by these versions of the operating system are not as important as to deserve this “sacrifice”. Anyway you cannot jailbreak iPhone 5 on iOS 6.1.3 or iOS 6.1.4.
Although it is possible that Apple have improved the battery life and other issues of the operating system to be solved, if you are satisfied with how the terminal operates on an older version, then keep it. If you have issues of functionality in an earlier version, then you can try out iOS 6.1.4 in an attempt to resolve the issue, although no guarantees that this will happen.
