'''IPSW''' ('''IP'''hone/ '''IP'''od Touch/ '''IP'''ad '''S'''oft'''W'''are) Files have the Magic Number 504B0304 (PK\003\004) and thus are [http://en.wikipedia.org/wiki/ZIP_%28file_format%29 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" redirects here. For the component of XPwn, see ipsw.

See also: Disk Image Formats

IPSW (iPod[1] 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). IPSWs are used to deliver the device's firmware to the end-user.

Archive Structure

Example

Here are the contents of the iPhone 3GS 3.0 (7A341) firmware IPSW:

Notes

  1. IPSW files have been used since the very first iPod, though they have a different format than firmwares for iOS devices.
