But as saurik points out, Cydia Impactor has a different objective.
It is the first tool that allows you to remove the jailbreak so you don’t have to restore your i OS device.
But ever since i OS 5, that's not true anymore.
Now you can install i Phone software updates wirelessly.
This might not be a huge amount of data and pose little problem, or it might be a lot of temporary files that eats a good portion of your 16GB i Phone’s memory. Ever made a warranty claim for a phone you had previously jailbroken?
saurik, founder of Cydia, has released a powerful new tool called Cydia Impactor.
For most, that option simply won’t work and others have reported experiencing battery life problems and activation issues when updating on top of a jailbreak.
More to the point, most i OS software updates modify your hardware’s baseband version, which means if you’re dependent on your jailbreak for an unlock, you will lose your unlock when you finally do upgrade.
Important: For this reason, you shouldn’t upgrade the software on your phone or restoring to stock if you depend on your jailbreak for an unlock.You can also do it right on the device, you don’t need a computer to do it.This can come in very handy when you want to sell your device, as it allows you to remove the data and all your personal data without having to restore your device.He has produced a wide variety of technical documentation, including detailed programming specifications and research papers.Randall has also acquired several years' experience writing web content. Unless you want a headache, battery problems or an i Phone that won’t even turn on, don’t simply attempt to upgrade over-the-air.
