Following the release of iOS 13.7 last week, Apple has now stopped signing iOS 13.6.1. This means that it is no longer possible to restore iPhone to iOS 13.6.1.
iOS 13.7 introduced just one big change ̵
Given how important contact tracking is to stop the spread of the ongoing pandemic, it’s important that you update your iPhone to iOS 13.7. There is no jailbreak available for iOS 13.6.1 for iPhone XS or later devices, which should further make the decision to upgrade to iOS 13.7 a little easier for you. For iPhone X and older devices, the Checkra1n jailbreak has also been confirmed to work with iOS 13.7.
iOS 13.7 is probably the latest iOS 13 release from Apple as the company is now preparing to release iOS 14 to the public. Apple has an event scheduled for September 15 where it will reveal the release date of iOS 14 to the public.
