First, it’s good to grasp what’s meant by the term” jailbreaking ” an Apple iPhone. As with all iPhones, Apple deliberately built features into each operating system [for example, iOS 5 for the iPhone 4s] which prevented users from downloading anything except from its own iTune or App stores. Put simply you were forced to buy all your various music and iPhone Apps from Apple.

Once an iPhone is jailbroken, any App can be downloaded from anywhere and there are countless millions of them out there, many for free and you can freely transfer films, games, videos etc directly from your personal computer. You then have complete access to a complete universe of great features and Applications all without having to go to, or pay, Apple.

There are two base kinds of jailbreak, being known as either “tethered” or “untethered”. In the tethered case, your iPhone needs to be connected to your personal computer every single time it’s rebooted and the jailbreak software run again in order to get it into the jailbroken state, or even to effect a reboot in any way. The difficulty here is if you don’t have access to a PC then your iPhone will be frozen into the Apple logo mode.

In the untethered case, once the iPhone is jailbroken then you can reboot it without having to connect to a compuer device with jailbreak software. This is obviously the more desirable type of jailbreaking and should be used when available.

There’s also a new hybrid jailbreak strategy known as semi-tethered which will let the iPhone to be rebooted without being connected tethered to a PC but such reboot can introduce heavy restrictions, for example Mail and Safari won’t work and many jailbroken installed Applications will crash on launch.

At the moment, untethered jailbreaking solutions are readily available for iPhones up to the iPhone 4, but not yet available in any stabilized state for the 4s [using iOS 5.0 or 5.0.1]. At this time there is a tethered solution, and even a limited semi-tethered solution, but it is definitely recommended to unlocking iPhone for the tethered version and do not bother to install these others unless you just can not help yourself!

It will not be long before the global network of super smart iOS jailbreakers/hackers find a stable and practical untethered solution for the iPhone 4s operating under iOS 5.0.

John Price, Ph.D. Is a well respected expert in the field of jailbreaking the iOS for various iPhone and iPad devices and for his contributions to the study of developing solutions for unlocking the iPhone 4s. His website explains the detailed differences between jailbreaking and unlocking and is complemented with a variety of testimonials.
