GestaltX: iOS 27.x MobileGestalt Editor, Supports 7 Languages

A mobile app for directly editing MobileGestalt files in iOS and iPadOS 27.x environments. Unlike existing methods that only read internal device cache files, it provides full editing capabilities, including adding, modifying, and deleting fields. It also supports importing and exporting local plist files.

You can adjust whether Apple Intelligence is enabled by changing the region code, and control display-related flags such as Dynamic Island layout and Always-On Display settings. It also offers presets for device defaults like model name, boot sound, and charging limits, as well as iPad-exclusive features such as Apple Pencil and Stage Manager.

Automatic backups and logging of original values are performed before applying any changes to prevent errors. You can compare and review the state before and after application, and immediately restore unwanted changes using the logged original values. It also includes a security measure that verifies device-specific identifiers to prevent the arbitrary import of plist files from other devices.

It supports 7 languages: English, Chinese (Simplified/Traditional), Vietnamese, Russian, Persian, and Korean. It operates exclusively on iOS 27.x, and access to internal device MobileGestalt is not possible on iOS 26.x or earlier. It is explicitly stated to be used only for security research and educational purposes, and users must accept the risk of system instability or the need for recovery.
