When talking about Cydia, it is of course referred to as a free to download program created with the sole purpose of providing free apps, wallpapers, themes and other software, for use with a jailbroken iphone or ipad. It was released in early 2008 by the creator Jay Freeman as an alternative to the very restrictive Apple iStore.
The DFU mode is the “Device Firmware Update” mode. In this mode the device can interact with iTunes without loading iOS or boot loader. This mode is different from the recovery mode and users use this mode to open up the device. When I say open up I don’t mean open up the device. A better term would be to say that the device can be unlocked so that one can use it for various purposes.
The DFU mode is used by those users that want to downgrade or upgrade the firmware of the iOS device. This is also the mode that is used to prepare the device for jail breaking.
The legality of jailbreaking has been attested to each within the field and in court, though it was officially ruled that it’s fully secure for the average user who decides to modify their device.

For users who want a a lot more robust and customized experience, jailbreaking delivers what stock devices do not.
