What happens to my apps when I unjailbreak my iPhone

Effects on Apps and Data

1. Restoring from Backup:
- If you unjailbreak by restoring your iPhone from a backup using iTunes, your device will revert to stock iOS. However, Cydia apps and any tweaks related to the jailbreak will be removed. You will regain access to the App Store apps that were installed prior to jailbreaking, but any third-party apps installed via Cydia will not be restored[1][4].

2. Without Backup:
- If you choose to unjailbreak without a backup, you may lose all data associated with the jailbreak. This method typically involves a complete wipe of the device, meaning that all apps (including those from the App Store) will be removed unless they are part of the default iOS installation[2][4].

3. Residual Jailbreak Files:
- Even after unjailbreaking, some users report that certain apps may still detect traces of the jailbreak due to leftover files. To fully remove these remnants, users often need to manually delete specific files or perform a factory reset without restoring from a backup[5][6].

4. Performance and Stability:
- Unjailbreaking can enhance the stability of your device and allow for future iOS updates, which might have been hindered by the jailbreak. However, if there are residual files or settings from the jailbreak, some apps may still misbehave or fail to function correctly until those are cleared[2][6].

Conclusion

In summary, when you unjailbreak your iPhone:
- Cydia apps will be lost, but App Store apps can be restored if backed up.
- Without a backup, all data may be wiped.
- Residual files can affect app functionality even after unjailbreaking.

For optimal results, consider backing up important data before proceeding with the unjailbreaking process.
