Part 4. More Questions about Jailbreaking iPhone

The following frequently questions from our subscribers, hope the answers can help.

Q1: Will jailbreaking brick my phone?

When you jailbreak your iPhone, you get root access to the filesystem of your iPhone. You will be able to install apps that were previously restricted by Apple. The only downside to jailbreaking your device is that you will no longer receive any official iOS updates from Apple.

Q2: What is Cydia? I’ve read many people recommending it on social media.

To make it easy to understand, you can regard Cydia as the App Store for jailbroken iPhone/iPad/iPod touch. So far the most commonly installed application for jailbroken devices. With the largest number of jailbreakers gathering on Cydia, it is the most recommended place to download apps and modifications. The infographic below illustrates Cydia in detail.

Q3: Is jailbreaking iPhone the same as unlocking?

Jailbreaking an iPhone allows you to install and use apps that are not present on the AppStore.

Unlocking an iPhone usually refers to the following occasions:

Screen unlock: remove the screen passcode (Face ID, Touch ID, password) to enter a locked iPhone

iCloud unlock: remove or bypass the step that requires previously used Apple ID and password

SIM unlock: would allow you to use your device with other mobile carriers.

What Does It Mean to Jailbreak an iPhone?

iPhone jailbreaking: What it is and how it works

To jailbreak your iPhone is to free it from the limitations imposed on it by its manufacturer (Apple) and carrier (for example, AT&T, Verizon, and others). After a jailbreak, the device can do things it previously couldn’t, such as install unofficial apps and modify settings and areas of the phone that were previously restricted.

Although the information in this article is specific to iPhones, it may apply to rooting Android phones, as well, regardless of who made those devices: Samsung, Google, Huawei, Xiaomi, etc.

Why You Might Want to Jailbreak Your Phone

Jailbreaking works by installing a software application on your computer and then having it transfer certain instructions to the phone so that it can essentially break open the file system. A jailbreak comes with a collection of tools that let you modify what otherwise could not be modified.

Jailbreaking lets you do everything from customizing the look of your iPhone to installing third-party applications, which are titles that are not authorized and available in the App Store. A third-party app can add functionality to your phone that you’d otherwise never see through the App Store.

By default, on a non-jailbroken iPhone, app developers are not allowed to modify certain parts of the operating system. However, when the OS is entirely open to developers working on jailbroken apps, you can find apps that can redesign stock apps like Messages, add widgets to the lock screen, and much more.

Depending on how far you’re willing to go, you can do even more. Jailbreaking even unlocks your phone so you can use it with a carrier other than the one from which you purchased it.

Why You Might Not Want to Jailbreak Your Phone

Once you jailbreak your phone, you’re entirely on your own since you may void the warranty you have with your carrier. This means that if something horrible happens to your phone, you can’t rely on AT&T, Verizon, or Apple to fix it.

Many users report an unstable or disabled phone after they enable the jailbreak. This is another reason you might want to avoid jailbreaking your device. Your smartphone could end up as nothing more than an expensive paperweight.

This is because there isn’t as strong of a standard when it comes to app development like there is with the official App Store apps. You might install a dozen customizations that end up crashing your phone or slowing it to a crawl.

Since developers of jailbroken apps can modify core components of the phone, it’s possible that a small change to an important or sensitive setting could completely ruin the software.

How to Fix a Jailbroken iPhone

Some users have reported that they were able to connect a malfunctioning iPhone to iTunes and restore it to its original settings, which resolved the problem. However, others have been left with a broken iPhone that doesn’t respond at all or reboots continuously until the battery dies.

Not all users have had this experience, though, but remember that you probably can’t count on AT&T, Verizon, or Apple to provide you with tech support once you take this unauthorized step.

Is It Illegal to Jailbreak a Phone?

The legality of jailbreaking your iPhone, iPod, iPad, or other iOS devices, sometimes changes as new laws are placed. It’s also not the same in every country.

To make a long story short, a jailbreak tool inserts specific files into your iPhone which causes the firmware modification. This modification is exactly what allows unofficial apps installation on your device.

Unlocking has nothing to do with jailbreaking. iPhone unlocking is about the removal of restrictions set by a carrier on your iPhone. Let’s say, you’ve bought your iPhone from a carrier, AT&T, T-Mobile, Sprint for US, or any other carrier in any country worldwide. This means you cannot use your iPhone with any carrier other than the one you’ve bought your device from. Once you unlock your iPhone, you are free to use it literally with any carrier anywhere across the globe.

It took a while for jailbreaking to be recognized legal in the US after struggle with Apple’s objections. This way, your iPhone jailbreaking is official and you can install any app you want on your device and no Apple’s permission is required to do so.

As you can imagine, unlocking is something causing financial losses for mobile carriers. No wonder that many of them weren’t happy about it. The good news is, that, despite carriers’ objections, unlocking is absolutely legal. So, you can switch and use services of any carrier you want. If it happens that you are not happy about the plans your current carrier offers, just unlock your iPhone and choose the carrier whose offers suit your needs the best.

2. Jailbreak will also allow you to install a wide range of Cydia repository tweaks on your iPhone.
3. Jailbreak will enable free tethering.

The ways you can use your iPhone become literally boundless after jailbreaking.

Speaking of unlocking, it has good reasons for you as well. Such as:

1. You want to switch a carrier because you are not happy about current plans offered.
2. You are going to move or travel internationally for a while and your current carrier’s services are not available where you go.
