Preview at WWDC likely in June, followed by September launch.
Video Walkthrough of iOS 7.1 Visual Tweaks and Improvements
Along with those major enhancements, the update also offers a slew of minor visual tweaks and improvements to the operating system, such as refined icons for the Phone, FaceTime, and Messages apps, along with revamped shift and caps locks keys and a new look for elements of the Phone app.
YouTube channel iTwe4kz has posted a handy overview of the new update, which shows off all of the new features that iOS 7.1 has to offer. The video has a detailed walkthrough of all the visual changes and enhancements, which is well worth watching for users who want a quick guide on what's new.
The full set of changes to the operating system were detailed in our initial post on iOS 7.1, which has a list of release notes directly from Apple and information on other app updates that were released today, including Xcode 5.1 and Remote.
As noted in the video, iOS 7.1 officially disables the iOS 7 evasi0n jailbreak by patching a key kernel exploit. iOS 7.1 is now available for all users via an over-the-air-update.
Update: The video was shot using an iOS 7.1 beta rather than the final public version, and also incorrectly depicts a change to the Photos app icon. The icon has not changed in iOS 7.1.
