Apple does not support sideloading on iOS 7. They consider any installation outside the App Store a violation of the iOS EULA. Jailbreaking remains technically legal in the US due to the 2010 DMCA exemption for smartphones, but that exemption has since expired. Still, no user has been sued solely for jailbreaking an iPhone 4.

| Feature | iOS 7.1.2 | iOS 18 | |---------|-----------|--------| | Signature requirement | SHA-1 / RSA 2048 | SHA-256 + hardened runtime | | Developer device limit | 100 per year (no automatic cleanup) | 10 per 7 days (free tier) | | App thinning support | None (universal IPA only) | Required (sliced IPAs) | | Installation via USB | Always allowed with any provisioning | Requires trust dialog + developer mode |

| Goal | What you need | |------|----------------| | Restore purchased apps (App Store still works on iOS 7.1.2) | Apple’s servers will offer the last compatible version of any app you previously bought. | | Install apps not in your purchase history (e.g., old games, tweaks) | You need to find archived IPAs from third-party sources — security risk and often requires jailbreak. |

For 95% of users, jailbreaking is the only practical way to run old IPAs without re-signing weekly.

Step 1 – Jailbreak iOS 7.1.2

Step 2 – Install AppSync Unified

Step 3 – Install IPA via Filza or iFunBox

Never download IPAs from unknown sources without scanning them. Malicious actors embed spyware, cryptocurrency miners, or device lockers into old IPAs because these devices often lack modern security patches.

This works for any app you previously owned. If you never owned it, you can’t force it.
