The Info.plist file can be viewed with a plist editor, Physical Analyzer, AXIOM, Inspector, XRY, or Oxygen Forensics. The Info.plist file is found in the backup directory and should always be examined to verify the data being parsed by the tool. The Info.plist contains the equipment identifiers, last backup date, phone number (if relevant), device name, device type, sync settings, build version, Backup folder name, applications, and so on.¹

Use caution here, as the last backup date in the Info.plist may be the date the tool (such as Physical Analyzer) acquired the device! In this example, that is exactly what happened. The real backup date is contained in the status.plist for this device.  If you were provided a backup file to examine and didn't know anything about the device, the items highlighted in the slide will assist you in your initial analysis.

Two examples of Info.plist files are provided below in both the xml and list views.
