What does it mean to jailbreak an iPhone

iPhone jailbreaking removes device restrictions implemented by Apple. Jailbreaking gives you root access to the operating system (iOS), which lets you install any software, remove default apps, and customize your phone beyond what is usually possible. Apple considers jailbreaking a violation of its license agreement. Jailbreaking your iPhone involves serious cybersecurity risks.

 

What is jailbreaking from a technical standpoint? Let’s answer that question in a bit more depth.

How does jailbreaking work

Jailbreaking an iOS exploits system vulnerabilities to gain root access to iOS. Jailbreaking modifies the kernel, the operating system's “central control system, " by running patches (or software modifications) every time you start the device.

 

This lets you install third-party app managers like Cydia to download apps unavailable on the App Store and make other system-level modifications otherwise prohibited.

Is it legal to jailbreak an iPhone

Jailbreaking an iPhone is legal in the United States and most other countries and jurisdictions.

 

Section 1201 of the Digital Millennium Copyright Act (DMCA) protects copyrighted works, including software. However, a series of exemptions by the US Copyright Office has made it legal for users to jailbreak their phones and other devices through a series of exemptions.

 

The US Copyright Office added iPhones to the exemptions list in 2010. It also included devices like smartwatches and tablets in 2015. Jailbreaking is not legal for installing illegally acquired apps (because of copyright laws).

Remember

Apple considers jailbreaking a violation of its user agreement and a basis for nulling an iPhone’s warranty.

How will Apple know you have jailbroken your iPhone? Does iPhone spy on you? The short answer is no. Apple is unlikely to collect data about your jailbreak status or to see if your iPhone is jailbroken. They can only know if you take your jailbroken phone into one of its shops for repairs.

Can someone jailbreak your iPhone without you knowing

It’s difficult but possible for somebody to jailbreak your iPhone without you knowing—they will need direct access and your passcode.

 

The other way somebody could jailbreak your iPhone is by hacking it remotely and installing jailbreaking software. However, this scenario is extremely unlikely.

 

Can an iPhone be hacked remotely? This is a complex question. While it is technically possible to hack an iPhone remotely, you are almost certainly not the victim of a remote attack. Conducting such an attack is extremely difficult and expensive and requires advanced tools and hacking skills.

 

If somebody has jailbroken your iPhone without your knowledge, the person responsible is likely in your immediate network. Consider that your spouse or a friend is tracking you.

 

Run a device scan with Clario Anti Spy to tell if your iPhone is jailbroken immediately.

What happens if your iPhone is jailbroken

If your iPhone is jailbroken, you gain superuser access, meaning you can interact with the operating system (iOS) however you like, including installing apps not available on the App Store. However, you open yourself to various risks, including data theft, malware, and tracking.

 

If your iPhone is jailbroken, it cannot receive normal iOS updates, and your warranty is no longer viable.

 

Your jailbroken iPhone may experience the following performance issues:

  1. Low battery
  2. System crashes
  3. Reduced speed
  4. Software bugs and device instability
  5. Difficulty installing the latest iOS version
  6. Limited access to saved app data
  7. Security vulnerabilities

Because jailbreaking circumvents many built-in security features, your phone is at greater risk of malware and hacking. Learning how to check for viruses on iPhone is important if you suspect your iPhone is jailbroken. In some cases, jailbreaking can lead to a “bricked” phone, which is completely unusable and difficult to restore.
