But as saurik points out, Cydia Impactor has a different objective.
You can install extensions that give you instant access to your system settings from anywhere on your i OS device, bypass certain restrictions set in place by Apple and the carriers, and find packages that give you more control over your i OS experience.
Jailbreaking is about freeing your i OS device from Apple’s restrictions to let you install anything you want.

Jailbreaking your i Phone allows you to install apps and tweaks that aren't allowed in the Apple App Store, which gives you more control over your i Phone but is frowned upon by Apple.saurik also has explained how the tool works: Impactor uses the firmware archives provided by Apple for its “over the air” update feature.These files are ~2GB large, so Impactor goes to extreme lengths to minimize the amount of data it needs to download: most recoveries will require less than 10MB of transfer.saurik, founder of Cydia, has released a powerful new tool called Cydia Impactor.It allows you to remove the jailbreak from your jailbroken device and return it to stock Apple i OS software without the need of restoring (updating) it.
