Safari has some minor changes in this version for Safari. The mapping app could see vital revamps on the iOS 6.1. Good news in this context is that the Apple bug that had been eating up into the JavaScript setting for the iPhone has been killed with the upgrade. The auto-change that was occurring with this bug caused a lot of users hassles. The update follows the previous upgrade to iOS 6.0.2 that took place in December. To check if your iPhone has got hold of the update check the Software Update tab under Settings.
