Quite simply stated, iOS jailbreaking implies carrying out a process of removing the limitations imposed by Apple within their iOS operating system. These limitations can be based on both, software as well as hardware parts. Limitations can be removed on both of them and removing this limitation or jailbreaking has now become utmost common for all your iPhones, iPads and even the Apple TV.
Studying underpinnings to Jailbreaking
Basically, iOS jailbreaking gives you the administrative root access to the file systems of the iOS. This allows you to download hundreds of additional applications or themes which might be unavailable through the official Apple store. Jailbreaking literally means breaking the device out of its jail.
One interesting point to be noted is that a jailbroken device can still avail the benefits of App store, iTunes, etc. but restoring the device with iTunes removes the jailbreak. So as one can see, the major justifications behind jailbreaking could be that it is done in order to expand the scope of the iPhone which is limited by Apple.
There is an application called Cydia which is installed during vast majority of jailbreaks.
In the year of 2007, a guy named George Hotz who went by the nick of ‘GeoHot’ managed to break into the iOS and managed to remove the lock which limited the whole scope of an iPhone or any Apple device for that matter. He removed the lock which granted the AT&T, the only rights to the very first iPhone.
This simple hack, as reported, enabled any SIM card across the world to take advantage of Apple’s iPhone.
Around that same time, a team referred to as the iPhoneSimFree presented instances of a working unlock which they had created which were never revealed to the public.
Subsequently, another team which went by the nick of ‘iPhone Dev Team’ was successful in providing another unlock and 2 GUI versions to it were subsequently released. These were AnySim and iUnlock Reloaded.
The ‘tech-giant’ responded
Towards the latter half of the year 2007, the Apple made an official statement stating that such unauthorized programs caused them “irreparable” damage and compromise the integrity of the iPhone and stated that the future versions would render the devices inoperable.
In the wake of their response, the update 1.1.1 which was released in the month of September in the year 2007 was virtually inoperable and was made available via the iTunes.
Jailbreakers didn’t stop
In the month succeeding the period when the 1.1.1 update came, the ‘iPhoneSIMFree’ team announced that they had jailbroke the 1.1.1 version too.
This jailbreaking was a benchmark in the sense that it didn’t just remove limitations, it also unbricked the phones which were rendered inoperable.
There was another team which went by the alias of ‘iPhone Elite Dev-Team’. In that very month when the SIMFree team had jailbreaked the 1.1.1 update, these guys released a tool giving the iPhone the ability to upgrade to 1.1.1 without their phone getting bricked.
Then, the Apple released the 1.1.2, again imposing the lock lifted by all the released tools.
In the light of all the breakings and the unbreakings, Steve Jobs said that,
“I’m not sure if we are the cat or the mouse. People will try to break in, and it’s our job to stop them breaking in.” Steve Jobs.
Next-gen jailbreaks : Oncoming of Cydia and Comex
In the year of 2008, PwnageTool released an update to their tool, the version 2.0, which supported the iPhone 3G. This update begun installing Cydia.
Cydia, which would go down in history as the most popular app which facilitated jailbreaking was launched in the February of that year as an open source alternative to Installer.app but since it got included with the PwnageTool, it was made available to a larger audience of the populace.
In the year of 2010, JailbreakMe 2.0 was released by Comex for iPhone 4. All you had to do to jailbreak your phone was that-
- You had to visit a website via. the safari browser in your phone.
- Then, you had to click the jailbreak button. Then, you had to wait for some seconds.>
- Your device got jailbroke into time.
Apple responded to this by releasing iOS 4.3.4 in the month of July, 2011 removing this unlock by Comex.
Then came the ‘Absinthe’ and ‘evasion’
All the strong jailbreakers out there collaborated to release ‘Absinthe’ which was a jailbreak tool for the iPhone 4S which was running the iOS 5. An update of the same, Absinthe 2.0 jailbroke iOS 5.1.1
The ‘evad3rs’ team released another tool, ‘evasion’ which jailbroke iOS 6.X and then the Apple upgraded it to 6.1.3.
The evasion tool had got an upgrade too, evasion 7.x which jailbroke even iOS 7.0.
As of now
In the year of 2103, another tool named ‘posixspwn’ was released on devices iOS 6.1.3 – 6.1.5 which required being tethered jailbroken using redsnow and an installation of Cydia.
iOS 7.1 was released in the wake of this jailbreaking which remained unbroken for some time until, Pangu, a Chinese jailbreak hit the Apple. They released the Pangu8 exploit which was untethered and jailbroke 7.1
In november 2014, the TaiG team released their tool with an update for devices running 8.0 to 8.1.1. This was updated later to include 8.1.2.
As of July 2015, TaiG 2.3.0 was released which included support for 8.0 to 8.4 iOS.
Currently, the apple iOS update stands at iOS 8.4.1 and the jailbreaking teams are working upon it in order to get a Jailbreak.
This was the history sketch of Apple’s jailbreak right since their first device penetrated the tech-arena.
