IPSW (IPhone/ IPod Touch/ IPad SoftWare) Files have the Magic Number 504B0304 (PK\003\004) and thus are ZIP Archives. They can be modified with typical zip/unzip tools (i.e. change extension to .zip and double click). An IPSW File is used to deliver the iPod Touch / iPhone firmware to the end-user.

IPSW Contents

root folder

  • \Firmware (Folder)

Firmware Folder

all_flash.XXXXX.production Folder

dfu Folder
