Today, I updated two iPhone units to iOS version '8.1.3'. If your device is Jailbroken, do not update. There's no known Jailbreak for it yet but otherwise, go ahead. Here are the changes:
*Reduces the amount of storage required to perform a software update
*Fixes an issue that prevented some users from entering their Apple ID password for Messages and FaceTime
*Addresses an issue that caused Spotlight to stop displaying app results
*Fixes an issue which prevented multitasking gestures from working on iPad
*Adds new configuration options for education standardised testing.
