Untethered Jailbreak and Tethered Jailbreak

[miniamber]

I don't want to sound dumb but I wanted to finally jailbreak my phone. I really want to use the tethering option. But I went on iClarified but I see something that says tethering and untethering jailbreak. When I read the different forums I see it to, what is the difference. Also what application do you use to tether i see something about tetherme and mywii (something like that) It seem like like this is getting alittle confusing.

Jailbreak: Getting root access to the device by “escalating user Privilege”, Privilege escalation is the act of exploiting a bug, design flaw or configuration oversight in an operating system or software application to gain elevated access to resources that are normally protected from an application or user. The result is that an application with more privileges than intended by the application developer or system administrator can perform unauthorized actions.

In iOS the user only have access to an specific area (commonly know as “Userland”) by the mean of a CHROOT jail, breaking out of this limitation allow regular user to scale to “root” (yielding the name Jail Breaking).

Tethered Jailbreak: is when a computer or another device (external Harddrive, modChip. etc) is required to inject the Jailbreaking code at boot. So once your iDevice is successfully jailbroken, you'll need to connect your iDevice to your computer if you ever need to reboot your iPhone or your iPhone loses battery charge.

Untethered Jailbreak: Means that the Jailbraking code live somewhere inside the iDevice and it can be invoke at boot without the need of any external device.

Internet Tethering and Jailbreaking tethered/untethered are not the same thing.

Tethered jailbreak means you will not be able to restart your phone without plugging it into a computer and running some software. Usually this is only necessary for early versions of a new jailbreak. You want an untethered if at all possible.


This is totally different and unrelated to "tethering" which is in reference to sharing your iPhone's internet connection with another device.
