Apple has released iOS 7 beta 4 to developers.
If you are already running iOS 7 beta, you can just go over to the software update menu and run the OTA (over the air) update on your device. It only takes a few minutes to download. After that, it will install, and you will be running the latest version of iOS 7 beta.
We will take a look and see if there is anything new worth mentioning. However, it’s probably just a few minor stability fixes.
