If you have come across the world of Jailbreaking, you should be know about the Terms “Tethered Jailbreak and Untethered Jailbreak and Semi Tethered Jailbreak”.The so-called “Tethered and Unthread” which has caused some confusion as to it’s definition. I’ll explain what a tethered jailbreak is versus an untethered jailbreak, and why one is better than the other.
Why you Should Jailbreak?
The main reason for Jailbreaking is to expand the feature set limited by Apple and its App Store. Jailbreaking is necessary if the user intends to run software not authorized by Apple. Some users look to software outside the App Store to express opposition to Apple’s censorship of content through the app approval process.Many Apps banned by Apple, due to the violations of iPhone Developer Program License Agreement.Including famous WikiLeaks App also banned for “violated their developer guideline”.Then Some people want to break these kind of restriction and rules made by Apple.Some users have found Jailbreaking to be a viable alternative to Apple’s censorship of content.Under the DMCA Act, Jailbreaking Apple devices is legal in the United States, although Apple has announced that the practice “can void the warranty”.
WHAT IS TETHERED JAILBREAK?
Tethered literally means ‘attached’,because they require a computer connection to boot a jailbroken iOS device.The tethered jailbreak is one in which a jailbroken iOS device cannot reboot when the battery dies(Complete Power off),you have to connect your iOS device back to your computer so that it can boot with the help of the jailbreak application like Sn0wbreeze. Such a device, if powered off, will go into recovery mode (or recovery loop) infinitely when rebooted unless it is attached to a computer and the same program that was used for jailbreak, will bypass the Apple logo and boot the device again.
What is the Need of Tethered Jailbreak?
Tethered jailbreak needs the help of a PC or MAC only because of the iBoot cannot pass the installed OS as genuine when booting in normal security check.It reads that as a modified (unsigned) one. The Jailbreak tool in your PC or MAC overrides iBoot itself, and so,security check will be bypassed and the OS remains as it was before, then you get the device booted.All your apps and Customizations won’t be modified;it will remain same.
WHAT IS UNTETHERED JAILBREAK?
An untethered jailbreak allows the device to be powered without computer assistance.It is the preferred jailbreak method because you don’t need computer assistance every time your iDevice Boots.You can reboot your iPhone or iPad as much as you want. If the battery dies on a device that has an untethered jailbreak, you don’t need the frustration, you just need charger and charge it again and it will boot as usual.
THEN WHAT IS SEMI-TETHERD JAILBREAK?
if you have a Tethered jailbroken iPhone and need to reboot it when you’re not near a computer… you might find yourself with an unusable phone until you get back to your home or office.semi-tethered jailbreak is a new concept which somehow sits in between the above two jailbreak methods . Semi-Tethered Jailbreak basically requires your device to be Tethered Jailbroken and then it helps you in a way that once your device turned off or battery dies you would have no choice other than rebooting with Redsn0w(connected with computer).
SemiTether lets you reboot a device that’s been jailbroken using a tethered message without getting stuck at the boot logo. Once you reboot you won’t have access to all of your device’s functions: You won’t be able to run jailbroken apps, the web browser won’t work, the Mail app doesn’t work, and some other apps may not function.
But you should be able to make calls or send text messages and use some built-in apps and that may be enough to tide you over until you can perform your next tethered boot.While hackers search for a way to perform an untethered jailbreak, SemiTether is probably the next best thing.
