IPSWFollowing the release of iOS 13.3.1 on January 28, Apple has stopped signing iOS 13.3, which means downgrading to that version of iOS is no longer possible.

iOS 13.3 was a major update that included Communication Limits for Screen Time, support for NFC, USB, and Lightning FIDO2-compliant security keys in Safari, and more.

Apple routinely stops signing older versions of software updates after new releases come out in order to encourage customers to keep their operating systems up to date.

iOS 13.3.1 is the current publicly available version of iOS, with the update introducing a toggle for the U1 Ultra Wideband chip in the newest iPhones along with various bug fixes and improvements.

Developers and public beta testers can also download iOS 13.4, an upcoming update that includes a new toolbar in the Mail app, iCloud Folder Sharing, new Memoji stickers, and more.

Conveniently there’s a jailbreak for A12/A13 devices being released in the next 24 hours that supports up to 13.3.

Any minute now Apple will activate the daily nag servers to notify all iOS users to install iOS 13 for us non-conformists. It's been quiet for a few weeks.
No kidding. Talk about living inside the nanny state....as a power user and someone who does NOT YET want to update my IP8 (and knows full well the 'consequences' for not being currently patched) I'm so tired of Cupertino telling me what I should be doing.
