What is RedSn0w?

Redsn0w is a free iOS jailbreaking tool from the iPhone Dev Team’s camp that allows users to jailbreak iPhone, iPad and iPod touch. When launched, redsn0w was introduced as ‘QuickPwn’ but due to the domain name misuse ‘QuickPwn’ was discontinued and tool was then named as ‘redsn0w’. Redsn0w also provides users with extra goodies such as enabling multitasking, wallpaper, and other features on certain iOS devices that otherwise not supported officially.

Tethered VS Untethered VS Semi-Tethered Jailbreak

Most of the iOS Jailbreakers are unaware about the terms often used by hackers – a tethered, untethered, and semi-tethered jailbreak. Let’s clarify what is the difference between them.

Untethered

This is the best option available to users but hard for hackers to achieve in every firmware update. It reboots your device without having to worry about it not booting up again. You can easily reboot your iPhone, iPad or iPod touch without any connection to a computer.

Tethered

A tethered jailbreak requires you to plug your jailbroken iPhone into computer and re-run the process to get your device up and running again, in case the battery drains out or you inadvertently shut-down your phone or you are forced to reboot it after having issues, or after installing a tweak that needs a reboot. Failing to do so will leave your device at the “connect to iTunes” screen.

You must be wondering why devices are tethered? This is because the device fails against some signature checks during the jailbreaking process. The device is able to boot up because there is a way to execute code via USB that allows you to bootstrap to a pwned iBSS, iBEC, or iBoot to finish the boot process without requiring any signature check.

Semi-Tethered

As the name suggests, semi-tethered jailbreak is an interim solution between the two listed above. When your device powers off after being jailbroken tethered, you will be unable to power it on. It will hang on the Apple logo indefinitely. It turns off fine, but it won’t turn on and you need to repeat the entire process again.

Big Boss has developed a new cydia tweak “semi tethered jailbreak” that lets you reboot your device and use stock apps on the iDevice but with some limitations. The tweak comes handy when you shut down the iPhone or iPod while travelling. With this little hack you are no longer stranded and you can reboot your device and use your phone, text, and many other features, which otherwise is not possible. Jailbreak tweaks and settings cannot be used until you boot tether your iPhone, iPad or iPod touch, however.
