Apple has today release iOS 10 Beta 3. This update brings quite a few bug fixes and a couple tweaks to the user interface. iOS 10 Beta also seems to improve performance as well and hopefully battery life too. iOS 10 is expected to release in the fall usually around the release of the next iPhone or iPhone 7 in this case. Check out the video for all the details.

Thanks
