Official jailbreak. What is jailbreak? Instructions for jailbreaking. Opportunities and risks of the procedure. Apple's attitude towards jailbreak

Surely each of you has heard such a word, understandable to many i-device owners, as jailbreak (from English Jailbreak is translated as “prison escape”). However, uninitiated users still do not know what it is. But it’s okay, we already have an answer to this question.

What it is?

Jailbreaking is an operation that is available for iOS (, iPad and iPod Touch), not supported by Apple, thanks to which any user can access the file system of their gadget. Look, the operating system runs all applications on behalf of the user with limited rights, so they can't have, say, access to all applications. In addition, applications only have access to a certain amount of memory allocated to it. This was done for a reason, but to ensure that it would be impossible to change important system data, which could lead to the loss of functionality of the device. In addition, thanks to this protection, you can install only those applications on the i-gadget that can be found in the AppStore.

What is it for?

Now imagine that the device has been jailbroken. What does this give?

• First, the user gets full access to the file system.

• Secondly, it can now add third-party software that is not available in the AppStore (for example, from Cydia).

• Thirdly, it becomes possible to add the gadget to BSD subsystems, which in turn includes SSH.

• Fourthly, thanks to unlocking, it becomes possible to use a phone designed exclusively for a particular operator by installing the necessary patches.

Types of Jailbreaks

There are two types - the so-called tethered and untethered.

• In the first case, after each reboot of the device it is necessary to jailbreak it, otherwise it may simply turn into a “brick”.

• In the second case, Jailbreak does not crash every time the device is rebooted, which is very convenient for its owner.

Technical side of the issue

In order for the user to be able to install additional applications, uses software called . We have already written about it more than once on our website, so this question We won’t consider it today.

It's time to draw some conclusions - Jailbreak is useful because it allows the user to compensate for all the inconveniences associated with the Apple license (for example, it allows the installation of other programs that are not in the AppStore or changing the duration of the ring tone on the iPhone). In addition, the user gets full access to the file system (this feature is natively present on almost all modern smartphones).

However, there are many disadvantages to be found here. For example, those applications that can be found in Cydia are not checked for security, so installing them can harm the device. And installing the OpenSSH package without changing UNIX passwords can provoke the theft of information from the gadget. Therefore, the user must answer the question whether it is worth doing a Jailbreak or not.

Rights

Oddly enough, from a legal point of view, Jailbreak is not a violation of copyright, but this does not apply to all countries, but most of them. From my side Apple company believes that jailbreak violates copyright, so after unlocking it refuses warranty repairs devices.

At the same time return factory condition The gadget is very simple - for this you need to use . It is believed that all traces of unlocking are completely lost, although no one can say for sure about this - there is an opinion that a firmware log is kept in a special section of the device, but this is just a hypothesis and no evidence has been found for it.

We talk about iPhone Jailbreak throughout our work, because without it you can install our programs for iPhone wiretapping - impossible! Most jailbreak instructions are written technical language and confuse people who want to do everything quickly and easily. Today I will try to tell you as briefly and simply as possible about this “scary” Jayle, what it is and how to make it.

What is jailbreak?

The iPhone, like other products, is designed to work only with Apple software. Therefore, there are a number of companies that are interested in increasing their profits and also managing the sales market for iOS programs. After the iPhone was released, hackers from these same companies came up with ways to change software phone so that third party programs had access to system processes apparatus. This is a jailbreak - it allows the owner of an iPhone to download any third party application from other companies.

There are 2 various types jailbreak – tethered (i.e., after rebooting the phone, the “jail will disappear”) and untethered (permanent).

How to tell if an iPhone is jailbroken?

Go to the applications menu and look for the Cydia icon. If you see this application, it means the jail has already been created on your phone.

I have selected links for you detailed instructions from their website.

Jailbreak is getting full rights to modify files in iPhone system folders. By analogy, is the acquisition of rights user root on UNIX-like systems.

Initially, when installing the original firmware, the user does not have the opportunity to edit important system files, and installed applications will be allowed to work exclusively with files in own folders(no program can add, delete or change a file that does not belong to it). Applications can only be installed from the store App Store, and therefore iOS is considered one of the safest operating systems into which a virus cannot be introduced.

Why is jailbreak needed?

Using this procedure, the user is able to install on iPhone apps, installation of which through the official appstore service and iTunes is not possible. The main source of such programs is Cydia.

Cydia- alternative store applications for iPhone like the App Store, only for devices that have undergone the jailbreak procedure. This is an application that contains information about Internet repositories (servers on which programs for iPhone are stored) with the ability to download, install and update various programs: from themes, screensavers and ringtones to the most serious applications. Almost all of these programs are free.

But perhaps the more important reason is the Unlock procedure ( iPhone unlock), for “unbinding” mobile phone from the operator. What allows iPhone to work with any SIM cards? mobile operators. This is relevant in countries where smartphones are sold under contracts, mainly with the USA.

All changes that occur to your phone's file system during Jailbreak are reversible and cannot lead to physical damage apparatus.

IN Lately Jailbreak's popularity is falling. This is evident from the statistics search queries Yandex.

Over the past two years, despite the huge sales of devices, the number of requests for jailbreak has almost halved.

The reason for this was the introduction of corporate developer certificates by Apple. This led to the emergence of services like Pgyer, from where you can download applications to the iPhone in Bypass App Store and without jailbreak.

In addition, unlocking devices can now be done quite officially. There are companies where for $20-30 you can unlink an iPhone from almost any operator with confirmation of this procedure on the Apple server.

How to jailbreak

Apple is constantly improving the security of iOS, which is why recently the lag between jailbreak releases and new firmware has increased significantly.

Jailbreak is divided into categories: tethered and untethered. The tethered one functions until the first reboot of the device, the untethered one works stably even after a reboot.

Apple's attitude towards jailbreak

Apple's official attitude towards the jailbreak procedure is: license agreement is violated and the owner Apple devices is deprived of the right to technical support And warranty obligations. However, legal proceedings in the USA led to the decision that a jailbreak is a deliberate software modification made by the user on a purchased device, and therefore it is unacceptable to consider it illegal.

In any case, you can carry out the iPhone firmware recovery procedure. After that, it is impossible to check whether the device has ever been jailbroken.

In this article we will try to tell you in detail about what jailbreaking is, its types, advantages and disadvantages. Verbatim Jailbreak translated from English as "Prison Break". Jailbreaking is a process in which it becomes possible free access to the file system, in simple words this is a hack iPhone firmware, iPad, iPod Touch.

How to do a untethered jailbreak on iPhone, iPad and iPod Touch.

In fact, “jailbreak” is translated as “jailbreak,” which seems to hint at the attitude of users of Apple gadgets to the company’s policy in the field of security and content management)

Actually, the point of the jailbreak procedure is the possibility of obtaining full access To system folders and files for reading and modifying their contents. Simply put, this is hacking the device’s firmware (more precisely, the file system). That's all. By default, on the original factory firmware, the user has access to only one directory ( /var/mobile/), where phone settings and media content are stored.

Why is jailbreak needed?

iOS security is achieved due to almost complete closure - the user does not have rights to change any files outside the “reservation” /var/mobile/, installed applications have the right to work with files only in their own directories, and the applications themselves can be installed only from one source - the mobile store Apple content App Store. Moreover, there are hundreds great apps, which Apple refused to place in its on-line store without explanation.

Jailbreaking allows you to bypass the above restrictions. The most interesting “consequence” of jailbreaking for the user is, of course, the ability to install applications from other sources. The source of “de facto” (as well as “must have”)) after hacking the file system is deservedly considered Cydia. Cydia hosts applications rejected by the App Store, as well as various “tweaks” system utilities, themes and ringtones. The majority of applications are free.

Another popular app Installous is intended for searching and installing hacked paid applications from the App Store on the device, naturally for free, which is pure piracy and is strongly condemned by the editors of the site.

The second most popular fruit of liberation is the ability to change the iOS interface within wide limits. For example, using the theme manager. With its help, complete modification is available system icons, switches, screens, etc.

Subtle “tuning” also becomes available operating system for advanced users, allowing you to optimize the operation of the device and extend battery life - for example, turn off background processes. Tools for fine tuning iOS many...

Jailbreak is also a necessary condition to unlock the device from the operator using software methods(unofficial).

How to jailbreak?

It is necessary to understand that jailbreaking is possible only thanks to the roteness of Apple programmers who allowed vulnerabilities in the system iOS security. To work with these vulnerabilities, hackers write so-called “exploits” ( exploits) - fragments program code, using the found system “holes”.

There are quite a lot of utilities that use existing exploits: redsn0w, Pwnage Tool, sn0wbreeze, Absinthe, Evasi0n, etc. They are easy to use and, as a rule, special skills are not required - instructions are publicly available on the Internet, including .

However, it seems that the concept of “jailbreaking” is gradually becoming a thing of the past - Apple programmers are consistently “patching holes”, neutralizing known vulnerabilities found by hackers with the release of new versions of iOS. We can say that both hackers and Apple programmers are working together to improve the iOS security system. This strange symbiosis has long given rise to rumors that hackers are supported by Apple)

Most likely, in the near future, the possibilities of “hacking” Apple devices may be limited only to hardware intervention - at the hardware level, which will definitely be closed to mass user, making it just entertainment for eccentric hackers. Congratulations to Apple)

Is jailbreaking legal?

There was a lot of discussion on this topic at one time - even at the level of the US Congress - the “Apple Corporation” went out of its way to ban this disgrace, since it suffered significant losses due to a lack of profit from its online content store (a couple of years ago, promptly everyone was hacked iOS versions And was a mass phenomenon).

However, legislators have decided that you are free to do whatever you want with your honestly purchased device - even throw it out of the window, even hack it. file system. But, naturally, there can be no talk of any guarantee after this procedure. However, the recovery is original firmware completely removes traces of jailbreak and deprives Apple of grounds for refusing warranty service...

Types of Jailbreak

There is tethered, untethered ) and semi-tethered. Short:

• If the jailbreak is tethered, then turning off or rebooting the device puts it into " eternal apple"and it can only be launched using a jailbreak utility using a computer. In fact, this is what determined the very appearance of the term “tethered” - you can’t go anywhere without a computer...

• If the jailbreak is “semi-tethered” - after a reboot the device will start on its own, but with some functional limitations - Cydia, Safari and previously installed jailbroken applications will not work. For full launch you should follow the procedure described above.

• If the jailbreak is untethered, the device can reboot painlessly and retain full functionality - the jailbreak does not crash.
