libimobiledevice is a software library that talks the protocols to support
iPhone®, iPod Touch®, iPad® and Apple TV® devices.

Unlike other projects, it does not depend on using any existing proprietary
libraries and does not require jailbreaking. It allows other software to
easily access the device's filesystem, retrieve information about the device
and it's internals, backup/restore the device, manage SpringBoard® icons,
manage installed applications, retrieve addressbook/calendars/notes and
bookmarks and (using libgpod) synchronize music and video to the device.
