iOS Signing Status

iOS signing status for every IPSW firmware release. Check which versions are currently signed, unsigned, and compatible with your device.

Apple is currently signing 14 iOS releases for iPhones — newest iOS 27.0.1 (released September 28, 2026), oldest iOS 4.1. The newest build alone still covers 34 iPhone models.

Anything not listed below can no longer be installed or restored — those files stay available for archival and research only. Download iOS 27.0.1 →

Apple digitally signs firmware versions to control which iOS versions can be installed on your device. This verification process only succeeds for currently signed firmware versions.

Once Apple stops signing a version, you cannot restore to it through standard methods. Apple typically signs the current version and sometimes one previous release.
