Icon Thief is a tool for retrieving the original app icons from an Apple device. It will organize and zip the icons, then attach the zip to an e-mail for easy retrieval without the need to use SSH.
The ZIP file of original icons can then be uploaded to a theme creator to assist them in making new icons that were previously missing from their theme!
The generated ZIP file is saved in the devices Documents folder. The exact location can be found in the “About” page in the app and will update dynamically for each device or IOS version. This is useful should there be a need to SSH into the device to get the ZIP file manually.
