What Does a Tethered and Untethered iPhone Jailbreak Mean?

That’s a ordinary discourse asked by newborn jailbreakers, and a hard one to eloquent by master jailbreakers. The stylish version of redsn0w 0.9.6b4 module jailbreak your iOS 4.2.1 device–but depending on which figure you have, your jailbreak module be either tethered or untethered.

Here’s the following account from the iPhone Dev Team:

Update #2:  The notion of a “tethered” jailbreak is pretty newborn to many people, so here’s a hurried summary on what to expect:

If you’re on an iPhone3G, old-bootrom iPhone3GS, or non-MC ipt2g, chronicle is easy. redsn0w installed an untethered jailbreak and so null beneath applies.

“Tethered” does not stingy you cannot rush at every without PC/Mac assistance.  If you hit not installed some tweaks that offer into essential programs same SpringBoard or CommCenter, your figure module actually boot. However, jailbreak programs same Cydia won’t impact (and Cydia haw ease hit a white icon).  Also, certain built-in apps that had to be touched by Cydia module change (Safari existence the most noticeable example).

If you’ve installed MobileSubstrate tweaks that offer into SpringBoard or other essential programs, your rush module actually change (you’ll intend stuck at the Apple logo). You requirement to ingest redsn0w to “Just rush tethered right now”.

Remember, @comex and others are working on a artefact to untether the 4.2.1 jailbreak. Meanwhile, the above 3 points hopefully module attain it every seem inferior confusing

A tethered jailbreak is not recreation to hit when installing tweaks via Cydia. Any revive module result in your iPhone requiring a Mac/PC to alter it again. Imagine yourself on the agency and your iPhone is rendered useless. Not fun. An untethered jailbreak is in the works, but it module take some time. I’m going to move it discover for my iPhone 4.
