Why do you need to jailbreak iOS? All the pros and cons. What is iPhone Jailbreak

Jailbreak(from English Jailbreak - “Jailbreak”) iPod Touch/iPhone/iPad is an officially unsupported Apple operation that allows you to open access to the file system in the device, similar to Microsoft ActiveSync. Which in turn makes it possible to expand the functionality of the device, for example, change the theme of tweaks, design, and most importantly install applications and games from other sources (not only from the app store App Store). Hacking tools are available to protect the baseband (GSM chip) with a special decoupling from AT&T, Sprint, Verizon.

After installation, the program has full access only to a certain part of the memory allocated specifically for the application (in addition, no applications are able to delete, change or add files that do not belong to it). The exceptions are contacts, videos, photos and music; the application has limited access to them after the user’s consent.

Tethered jailbreak

It needs to be done again after the next reboot of the device; there is no need to reinstall the application.

Untethered jailbreak

Does not disappear after rebooting the device, unlike the tethered jailbreak described above.

Semi-tethered jailbreak

Allows you to reboot the device without losing the ability to use it, however, after new download The device's jailbreak functions are lost.

Installing Jailbreak on iOS6

While the hackers from Evad3rs have not announced a release date for the updated hacking tool, the existing vulnerabilities will probably only be used for iOS 7.

In this regard, the owners of all the latest gadgets With installed iOS 6.1.3, and these are: iPhone 4S, iPhone 5, iPad 3, iPad 4, iPad 2, iPod Touch 5G and iPad mini We just have to wait for the release of the next untethered jailbreak.

Owners of older devices: iPhone 3GS, iPhone 4, and iPod Touch are much more fortunate. They can also be jailbroken to iOS 6.1.3, but this jailbreak will be tethered.

A tethered jailbreak is a jailbreak of an iOS device that functions until a reboot. Devices with a tethered jailbreak can function the same way as one jailbroken using evasi0n, but after a reboot, it can only be launched thanks to the computer and the Redsn0w application (otherwise it will not start). That's all the differences.

With help from Redsn0w

Step 1: Download official firmware iOS versions 6 and install on iPhone 3GS/4, iPod Touch 4.

Step 2: Download for your operating room Windows systems or Mac from the iPhone Dev-Team website. Unzip the downloaded file into a separate folder, then run Redsn0w.

Step 3: In the main menu, click on Extras (Select IPSW), specify the path to the downloaded file iOS firmware in step 1.

Step 4: Select “Back” and click “Jailbreak”. Make sure Install SSH is checked and your iPad, iPhone or iPod touch turned off and connected to the computer, then click “Next”.

Step 5: Click on the jailbreak button, then follow the instructions on the display. The Redsn0w program may require you to enter your device into a special DFU mode, for this you need:

• Turn off the device;
• Turn off iTunes;
• Hold down the power button for 3 seconds, and after 3 seconds, while continuing to hold down the power button, click on the “Home” button;
• And after 10 seconds, release the lock button while continuing to hold the Home button.

Redsn0w will jailbreak iOS 6 very quickly. And after auto-rebooting, you will get an iPhone, iPad or iPod touch on iOS 6 with the jailbreak installed.

Loading in tethered mode

Now when you reboot your iOS device, you will need to connect it to your PC and put it in new mode jailbreak using Redsn0w 0.9.13dev4 function. You need to open the “Extras” category and click on the “Just boot” button.

How to install Cydia

This version of Redsn0w does not install Cydia when jailbreaking, the entire installation of Cydia will have to be done manually.

All the necessary commands for installing Cydia via a secure SSH shell were performed in the Terminal application for Mac OS X. Owners of Windows computers will be able to use similar commands in WinSCP. Next are the instructions.

Step 1: You need to select “Wi-Fi” in the “Settings” menu and click on the arrow next to the network name. Copy your IP address, for example 192.168.2.64. (Check whether the gadget is connected to the computer using wireless network. It is recommended to disable the firewall and antivirus).

Step 2: B special application or in the terminal, enter the code: ssh root@”device IP address”, for SHH connection of the device (for example: iPhone).

Step 3: Enter the default password. (You can also use other programs to connect to the device, Putty on Windows and Coda on Mac.)

Step 4: Enter the command (via SSH):

wget -q -O /tmp/cyinstall.sh http://downloads.kr1sis.net/cyinstall.sh && chmod 755 /tmp/cyinstall.sh && /tmp/cyinstall.sh

Step 5: The device will respring, after which the Cydia icon will appear on the screen. Launch the store, it will prepare the file system for use.

Now you can install tweaks and applications from Cydia.

Note: Redsn0w 0.9.13dev4 is not able to jailbreak iPad 2, 3, iPhone 4S based on A5X and A5 chips.

How to jailbreak iPhone 5, 4S, iPad and iPod touch

• Step 1: Download the latest iTunes versions and Evasi0n.
• Step 2: Update your iPhone, iPod touch or iPad to new iOS 6.1.2 via iTunes.
• Step 3: Connect your device to your computer, open iTunes or iCloud and do backup information. You also need to disable the password on the lock screen, go to the Settings menu -> next General -> Password protection -> and Disable password.
• Step 4: Evasi0n will display the model of your gadget. Click on the “Jailbreak” button in the program. Now the application will do the injection, install the Cudia store and reboot the device. Do not interrupt the installation procedure and do not turn off the gadget from the computer at this moment!
• Step 5: After the message “To continue, please unlock your device and tap the new ‘Jailbreak’ icon”, unlock the gadget and find the “Jailbreak” icon on the desktop, click on it. The gadget's screen will turn black for a moment, and then a springboard will appear.
• Step 6: Next, the jailbreak continues: you will notice in the program window information about jailbreaking your device. After the message Done! close the application. Yours iPhone device will reboot. Please note that the launch process will take a long time.
• Step 7: And now, after the phone boots up, the Evasi0n logo will appear on the screen. Your iPad or iPhone will reboot a second time.

That's it! You have jailbroken your iOS device.

Question-Answer

What is jailbreak? Is it harmful? Is it possible to jailbreak?

No, it is not harmful, and in some cases it is the opposite. By jailbreaking your device, you can install software packages not signed by Apple that can change the functionality of the device.

Will I be able to buy music and apps on the App Store?

Will my early purchases be lost after the jailbreak?

No, nothing will happen to your Apple ID, you will continue to use the device as before.

There are opinions that the device begins to slow down due to jailbreak. This is true?

No, it will not slow down the device.

What is a tweak?

A tweak is a small program that adds functionality and ease of use of the device. For example, quick settings in a special Notification Center.

Jailbreak is such a familiar unfamiliar word, and so much is said about it, but it is not entirely clear what it is. For many, this term is associated with hacking, pirated content and the obligatory damage to a smartphone. Some people shy away from this word as if it were leprosy. Yeah, well, it’s not worth it...

After all, there is nothing terrible in this procedure - it is just an official hack of the iPhone operating system, allowing the user to return the wings that were so cruelly clipped by Apple developers. And the question of the sinfulness of jailbreaking an iPhone can be safely left for forum verbiage.

What is jailbreak? Jailbreak, also known as “jail”, is an official procedure that opens free access to file system on Apple devices, and thus expanding their capabilities. “Official” does not mean that Apple personally initiated this proposal, but, in any case, at the legislative level it cannot prohibit it. All she can do is threaten freedom-loving users with a lack of technical support and warranty repairs, but even then, according to the laws of the Russian Federation, in the event of a breakdown, not through the fault of the client, the smartphone is required to be repaired under warranty. So the intimidation is purely symbolic.

Moreover, it is absolutely not difficult to roll back this procedure, returning virginity to your sensory pet. In the warranty service, everything will look as if there was no Jell-O and along with it tons of pirated content.

There are two types of jela - tied and untethered. It is better not to consider the first one at all. The fact is that a linked phone only works for the duration of one session, i.e. after turning it off, it goes away, and then it needs to be done again. Moreover, the system begins to completely lose self-control. And after turning it on, it either does not start at all, or only works partially - some applications are “silent”. But it comes out almost on par with the new version of iOS.

But it is better to wait for the release of an untethered jailbreak. The name speaks for itself - it is not tied to a session and gives a more sustainable result, working seven days a week. And it does not cause problems in the system. As a rule.

Pros and cons of jailbreaking

Well, what exactly is this “prison escape” for and how much do they pay for it? Not at all, the main thing is to erase traces of the crime in a timely manner. Okay, it’s not good to cheat, and there are disadvantages, so after weighing all the pros and cons, the user himself will make an informed decision.

So, why do you need jailbreak:

Well, why not do such a useful action? What is the argument made by the fighters for the rights of Apple and all disadvantaged authors?

So, here are the disadvantages:

How to find out if your iPhone is jailbroken

How to check if there is a jailbreak for iPhone 4, iPhone 5s - or for any other model?

Cidia http://www.cydiaimpactor.com/ is a pirated application that can hand over a junked iPhone with its head sometimes wisely hidden. The shortcut is placed in a separate folder or hidden using special tweaks. But the program itself does not go anywhere, so it is easy to determine through a search.

You can check this using iFunbox. It is installed on the computer, after which the iPhone is connected, and in the device line you need to look if there is the word “Jailed”. If it is there, it means there is no gel. The absence of this word should be stressful, especially if tomorrow you are carrying a toy to warranty repair. After all, the model is probably already jailbroken.

How to install jailbreak on iPhone

It should be immediately noted that for each iPhone model, or, more precisely, the version of iOS that it supports, there is its own way to perform a phone call. If the method is chosen incorrectly, you can easily ruin the device. Therefore, if you are not sure that your favorite iPhone 5s or higher does not support this phone, it is better to use third-party services. Or install exactly the version described in the instructions for the Jel. There is probably no need to explain how to update the “axis”.

Jailbreak iPhone 3gs

The method works on iOS 6.0, but may not work correctly with version 6.1. Moreover, the installed hack will be tied and after each reboot the process will need to be carried out again. But the problem is solved by installing p0sixpwn from Cydia.

Algorithm of actions:

• The Redsn0w 0.9.15b3 utility is downloaded.
• The iPhone is connected to the PC, after which Redsn0w is launched (as an administrator).
• In the window that opens, select Advanced > IPSW > IOS 6.0 IPSW.
• Return to the main page and click “Jailbreak”.
• Select Install Cidia and click Next.
• The smartphone is introduced into DFU mode(you need to confirm the action), and the program itself brings the JJ process to the final stage, reporting the execution of the linked JB.
• Then click OK and the process is completed manually - based on the instructions.

Jailbreaking an iPhone 3g follows similar instructions (without step 3) and the only difference is that iOS 4.2.1 “breaks”.

How to jailbreak iPhone 4s and iPhone 5s

The order is as follows:

• Download and install the Pangu utility. As already mentioned, it works on iPhone 4 and iPhone 5s, or rather, with the operating systems that they support.
• The program starts, the iPhone is connected - if the system is suitable, the treasured Jailbreak button lights up.
• Now you need to click on it - after which the smartphone will be prompted to change the system date. The program will tell you exactly what needs to be done.
• A Pangu shortcut will appear on your smartphone - you need to launch it and continue “breaking”. Or rather, the program will do it itself. Once completed, it will turn into the Cidia icon.

Yes, it’s all like this – very, very difficult.

Jailbreak on iPhone 6/7

As you can see, an iPhone 4 or iPhone 5s is, of course, not difficult to hack. What should owners of later versions of iOS do?

And everything has already been done for them. So, first you need to download the files:

• Yalu ipa file https://mega.nz/#!W10jGaIZ!_Ph1J327fNlVPIS6Bq-cWVF…
• Cydia Impactor

• Now you need to connect the device to the PC via the latest iTunes;
• Cydia Impactor starts - it’s better to first save files from the iPhone to the cloud;
• The device is selected.
• Yalu is dragged into the Cydia Impactor window.
• A window will appear - you need to enter Apple data ID. It's better to create another account first.
• The action is confirmed - after that you need to go to the settings in the device management section and allow the developer account to be trusted.
• Now you can launch the mach_portal application that appears and rejoice. But only until the next time you turn it on, because then you will have to launch this application again. Jel is semi-attached, there is no other one yet.

How to remove jailbreak from iPhone

How to remove Jailbreak? It's very simple. You just need to update your operating system via iTunes. Updated iOS removes Jailbreak from iPhone without a trace. Before you remove it, it is better to first make a backup copy of everything on your smartphone to ICloud.

Conclusion

Yes, everything is quite simple and does not require a lot of time or intellectual energy. The only question is: why buy an iPhone and “break” it when you can buy a less strict device?

Yes, Apple is about quality, it is about status, after all, it is the brainchild of Steve Jobs himself! This is truly a cult thing. Therefore, you should buy it and then “break it” - no one will see it, and the outwardly fashionable gadget will remain the same. Overall, there's a lot to think about here.

If you are iPhone owner or iPad, you may have probably heard about the so-called Jailbreak. This word can be translated from English as “escape” or “prison escape.” What does this term mean?

Jailbreaking is an operation that allows you to gain access to the file system of a number of Apple devices, including the iPad, iPhone or iPod Touch. This procedure expands the standard capabilities of the device: in addition to access to the file system, the user receives, for example, the ability to install applications not from the App Store or change themes.

How to jailbreak?

In order to gain access to the file system, you need to use special utilities that allow you to do this very jailbreak. These include programs Pwnage Tool, redsn0w, sn0wbreeze, etc.

Most often, the process is very easy: the user downloads the application to the computer, connects his device to it, launches the utility and performs several simple actions. The utility does most of the process itself.

In other cases, the application is installed on the device itself.

Why do you need jailbreak?

Above we described a couple of advantages of jailbreaking, now let’s dive into this topic in more detail.

The first important advantage is the shops third party applications. The leader among them is Cydia. There are many applications in Cydia that, in one way or another, could not get into the App Store. Most of them are free.

Not all users need access to the file system, but many people like the ability to change many things on the desktop. So, the Springtomize application has large number options for customizing folders, icons, desktops, lock screen, status bar, etc.

And many people probably dreamed about changing the theme, which is easy to do using third-party applications from the same Cydia.

As you can see, there are many advantages and these are just some of them, but remember that Jailbreak also has disadvantages.

Disadvantages of jailbreak

Now let's talk about the disadvantages, there are several of them and they are all very important.

First and foremost, iOS is one of the most secure operating systems, including due to the fact that the user’s access to the file system is denied. If access to it is open, which happens with jailbreaking, picking up a Trojan or virus becomes much easier.

Second. Installing Jailbreak may cause problems with the device. Sometimes it happens that an iPhone or iPad turns into a “brick”, often due to the fault of the user if he did not perform the action that he sees on the screen during the jailbreak procedure. Responsibility for this, of course, lies solely with the owner of the device.

Third - Jailbreak deprives iPhone warranty or iPad. True, this only applies to those cases when jailbreak is used. If you reflash the device without jailbreaking, traces of hacking will be removed.

What does Apple itself think? The company speaks out against Jailbreak, which is understandable. Therefore, with the release of each new iOS updates To jailbreak, you need to wait for the release of a new utility, since the previous “holes” are closed by the developers.

Is jailbreak really necessary?

In our opinion, it is better not to jailbreak, because in this case the warranty is lost, and it is also easier to stumble upon a malicious program or Trojan while wandering the Internet. But this, of course, is up to the owner of the device to decide.

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

Initially, when installing the original firmware, the user does not have the opportunity to edit important system files, A installed applications are 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 are installed only from App store 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 applications on the iPhone, the installation of which through official service appstore and itunes is not possible. The main source of such programs is Cydia.

Cydia is an alternative application store for iPhone similar to 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 the file system of your phone during Jailbreak are reversible and cannot lead to physical damage to the device.

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 decreased by almost half.

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, bypassing the 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 jailbreak is a deliberate modification software, performed by the user on the purchased device, and therefore it is unacceptable to consider it illegal.

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

Jailbreak- receiving full file system access iOS devices. iOS, which powers the iPhone, iPod touch, iPad, and Apple TV, is considered one of the most secure operating systems for good reason. iOS security is achieved by being closed: programs can be installed from only one source (the App Store), installed applications are only allowed to work with files in their own folders, and the user is not able to edit any important system files.

Jailbreak, which literally translates to "jailbreak" in English, allows you to bypass all Apple restrictions and allow access to any files inside your iPhone, iPod touch, iPad or Apple TV.

How is jailbreaking done?

Jailbreaking devices is possible due to security vulnerabilities in iOS. To use these exploits, special utilities- for example, redsn0w, sn0wbreeze, Pwnage Tool, Absinthe, etc. As a rule, user participation is reduced to a minimum - he just needs to connect his iPhone, iPod touch, iPad or Apple TV, enter the gadget into desired mode and wait for the jailbreak to complete in the appropriate utility.

Instructions for all existing methods jailbreaks are collected in the Encyclopedia of Jailbreak and Unlock of the AppStudio project, which you are reading now. You can find the method you need and instructions for it by following the link:

What are the benefits of jailbreaking?

Firstly, jailbreaking gives you the ability to install programs not from the App Store. Over the years, different sources of third-party applications for iPhone, iPod touch and iPad have appeared - Installer, Rock Your Phone, Icy, but for quite a long time the main (and in fact the only) alternative store applications is Cydia- project of Jay Freeman (aka Saurik). Cydia has thousands of third party programs, add-ons and tweaks, most of which are free. Cydia hosts those programs that are not included in the App Store due to strict Apple restrictions, For example:

• iFile- full-fledged file manager for iOS, which on jailbroken devices plays the role of Finder or Explorer, allowing you to perform all basic operations with files and work with archives

• SBSettings- a utility that provides quick access to various switches, with which you can turn on or off 3G, Wi-Fi, GPS, cellular data transfer, adjust brightness, clear RAM etc.

• Springtomize 2- a universal control center for iOS interface tweaks, where you can change the number of icons in the dock, add columns and rows to desktops, adjust animation speed, increase the capacity of iOS folders to infinity and much, much more.

• BiteSMS- an alternative SMS client for iPhone, which integrates into the system much deeper than standard application, and has dozens of additional features.

The list can be continued for a long time.

Secondly, jailbreaking allows you to do things on your own. iOS tweaking for your own needs. For example, you can significantly extend the battery life of your gadget, or quickly translate words in Safari, iBooks and other programs. Opportunities for additional settings iOS - mass.



Thirdly, jailbreaking opens up great opportunities for iOS interface changes. With the help of the Winterboard theme manager, you can choose a completely different design style for the system interface - from replacing the dock to completely modifying all system icons, switches and screens.



Fourthly, although I don’t really want to write about it, jailbreaking makes it possible to install pirated applications on the iPhone, iPod touch and iPad. It is enough to replace a number of system iOS files, and code signing verification is disabled, allowing you to install applications that were not purchased from the App Store. Alas, in the minds of many users, jailbreaking is associated precisely with piracy, although the jailbreaking procedure itself does not mean hacking applications. However, in 2015, this argument lost its meaning, because Apple allowed the installation of re-signed (including jailbroken) applications on devices without jailbreak for anyone who has Mac OS X at hand.

You can find a detailed selection of good tweaks from Cydia, selected by our editors, here:

You can read about what useful jailbreak provides to Apple TV owners in.

Why is jailbreaking dangerous?

First, jailbreaking significantly increases the risk iOS release out of order. Since all system files are available to the user, their thoughtless modification may cause the gadget to stop loading, resulting in the need to restore the firmware.

Secondly, jailbreaking involves risks to the security of your data. Although there are no iOS viruses yet that infect jailbroken iPhones, iPod touches and iPads, corrupt them or steal users’ personal information, the possibility of their appearance cannot be ruled out.

Third, jailbreaking formally voids the warranty on the iOS device. If you take it to service center and they will find out that the gadget has been jailbroken, and they will refuse you service. Fortunately, restoring the firmware completely erases all traces of jailbreak.

Is jailbreaking legal?

There has already been a debate about this, even at the level of the US Congress. As a result, a completely reasonable point of view prevailed: jailbreak is a deliberate modification of a gadget’s software made by the user on a purchased device, therefore it is unacceptable to consider it illegal. Simply put, with your iPhone, iPod touch, iPad or Apple TV, you are free to do whatever you want - even jailbreak, even drowning, even throwing out of a window;)



How often does jailbreak appear?

Alas, lately between the release new version iOS and the advent of jailbreaking for it are passing more and more time. Apple programmers are constantly improving iOS security, closing more and more new vulnerabilities, so finding new ones is becoming more and more difficult every year. By the way, another argument in favor of jailbreaking is connected with this: if no one did it, Apple would have no idea how many holes could be found in the security of their mobile operating system.
