Basically, iOS jailbreak allows you to get full or technically root access to all functionalities and features of the device you are jailbreaking. so, jailbreak of iOS will make you able to grant root access to all the features that Apple doesn’t allow you to get them for for free.

Apple announced the release of iOS 5 quite a few days ago, but when people were looking for iphone 5 they came out with iphone 4s. The second iOS5 beta has been released last week and it indicates that Apple has stepped up their game to protect it from jailbreaking. According to iphone Dev-Team(the group that makes jailbreaks), Apple has changed the iOS boot sequence to require a signed authentication ticket which still requires to be hacked. This approach renders current untethered jailbreaks, applied in tools such as Pwnage Tool and Redsn0w, almost useless for iOS 5 at very moment. As Apple is really ramping up measures against iOS 5 jailbreak, dev-Team one more time brought jailbreak for diehard fans and ios diehard fans happy.
We do have to wonder everything that Apple really thinks about jailbreaking. On one hand I’m confident that they’d wish to stop this completely, but on the other side that percentage from device owners carrying it out is very small it really is probably something they can afford to ignore. Even though, Apple’s iOS squad will carry on and close the particular exploits that help jailbreak on every release while in the hope it will stop these individuals from transpiring. I doubt that may ever be the case, though.
