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:
