Currently, Apple prevents users from installing older iOS versions by restricting firmware signing (SHSH blobs). This limitation is not due to technical constraints but rather a corporate decision. iPhones are fully capable of running older versions of iOS, as demonstrated by the jailbreak community and independent testing.

Our Arguments:

1. Right to Choose – Users should have the freedom to decide which iOS version to use, especially when newer updates slow down their devices.

2. Performance and Stability – Older iOS versions often run smoother on older hardware. Forced updates lead to performance issues and reduced device lifespan.

3. App Compatibility – Some apps work better or are only available on earlier iOS versions. Users should have the option to tailor their system to their needs.

4. Preserving Technological Heritage – Keeping access to older iOS versions allows for archiving and analyzing Apple’s system evolution, which has historical and educational value.

5. Device Repair and Longevity – The ability to revert to previous iOS versions can help save devices affected by faulty updates or compatibility issues.

We urge Apple to respect user choice and allow iPhone downgrades officially.
