Apple Stops Signing iOS 13.3 Following iOS 13.3.1 Release

Apple released iOS 13.3.1 back January, and as is traditional, Apple has now stopped signing iOS 13.3, making downgrading to that version of iOS no longer possible.

Apple is known to stop signing older versions of operating systems after it releases a public update, as part of an effort to encourage users to keep their devices’ operating systems up to date.

Apple’s decision to stop signing iOS 13.3 should be of particularly sour news to jailbreak users, The unc0ver team has teased that a jailbreak for iOS 13.3 is on the way sometime this week.

This means that users on iOS 13.3.1 looking to jailbreak are now stuck on the newest version of iOS and can’t downgrade to use the jailbreak tool once it is released.

iOS 13.3.1 is the current public version of iOS, and includes the following new features and fixes:

  • Fixes an issue in Communication Limits that could allow a contact to be added without entering the Screen Time passcode
  • Adds a setting to control the use of location services by the U1 Ultra Wideband chip
  • Addresses an issue that could cause a momentary delay before editing a Deep Fusion photo taken on iPhone 11 or iPhone 11 Pro
  • Resolves an issue with Mail that could cause remote images to load even when the “Load Remote Images” setting is disabled
  • Fixes an issue that could cause multiple undo dialogs to appear in Mail
  • Addresses an issue where FaceTime could use the rear-facing ultra-wide camera instead of the wide camera
  • Resolves an issue where push notifications could fail to be delivered over Wi-Fi
  • Addresses a CarPlay issue that could cause distorted sound when making phone calls in certain vehicles
  • Introduces support for Indian English Siri voices for HomePod
