How to Tell if Your iPhone Is Jailbroken

While it sounds like something you might see in a Western, jailbreaking is actually the act of altering your iPhone so that you can bypass the software restrictions imposed by the iOS operating system.

Jailbreaking originally came about to give Apple mobile device owners more freedom in how they use their devices. It enables you to make changes to in-built features or download apps that haven’t been cleared by the official App Store.

As you might expect, Apple is against this practice, and they have worked extensively to try and limit the ways in which you are able to jailbreak your phone. However, it is still possible to crack the code.

The practice has had a bit of a resurgence in recent years with a number of new tools released to the market, including Palera1n, which enables jailbreaking of many devices even if they are fully up-to-date.

While jailbreaking gives you more freedom, it also exposes you to increased risks of security breaches and hacks. We spoke about the risks and rewards of jailbreaking an iPhone in an earlier blog, which you can read here.

There is a notable correlation between jailbreaking and spyware. Most commercially available iOS spyware requires your device to be jailbroken in order to function as it allows a hacker to install unofficial apps onto the device.

This means that if someone has successfully jailbroken your phone without your consent, not only can they monitor your activities using spyware but they are also exposing you to other forms of malware.

Is My Phone Jailbroken? Here’s How to Tell

If you suspect your iPhone has been jailbroken or unlocked and are concerned about your privacy and security, there are a number of ways in which you can check your device:

1. Cydia or Sileo are installed

One way to confirm if your iPhone is jailbroken is to look for an app called either “Cydia” or “Sileo”. These apps are in fact third-party app stores that are usually installed during the jailbreak process. However, it is also important to note that on a jailbroken device, any app icon (e.g. Cydia/Sileo) can be made invisible to the user so it is not a fool-proof method of detection.

2. Other unusual apps

It is also important to check for any other unusual apps that have appeared on your home screen that you haven’t downloaded yourself. Many jailbreak tools include a launcher app which can be run to re-jailbreak the device if the jailbreak has been removed.

An example of one of these apps is “checkra1n” which is often installed alongside one of the most popular jailbreaks. If you find an app that you’re not sure about, you should try Googling its name and it should tell you if it’s related to a jailbreak tool.

3. Run a Jailbreak scan

While the first two checks can be a good indicator that you might have a problem, neither of these methods are a fully effective way to see if your phone has been jailbroken without your knowledge. One way in which you can be sure is to run a FREE check with Certo Mobile Security. The app will scan your phone, confirm whether it has been jailbroken and identify any other security threats.

How to Remove a Jailbreak

If you find that your device has been jailbroken, and you didn’t do this yourself, then it’s likely that this was done with malicious intent. As a result, you will want to secure it as soon as possible. By removing a jailbreak, you are able to put a stop to any apps that rely on it to function, protecting you from spyware.

There are a couple of ways you can remove a jailbreak:

1. Perform an iOS update on your iPhone

To do this, open the Settings app on your device. Then tap General > Software Update. If an update is available, tap Update Now to install.

2. Perform a factory reset on your iOS device

To do this, plug your iPhone into a computer and open iTunes (Windows) or Finder (Mac). Tap your device then select the Restore iPhone option. However, make sure you create a backup of your device before doing this. And don’t worry, the Jailbreak won’t carry across in the backup.

Final Thoughts

Hackers with malicious intent not only do you harm for their own means, such as monitoring your activity or stealing personal data, but they also don’t care what other threats they expose you to. Jailbreaking your phone creates increased risk from security breaches and can invalidate your warranty.

By remaining vigilant and using apps such as Certo Mobile Security, you can mitigate both the risk from malicious actors and the collateral damage that they cause.

Frequently Asked Questions (FAQs)

How can you find Cydia on iPhone?

Cydia is a third-party app store that is commonly used on jailbroken iPhones as a way to download unofficial apps.

The quickest way to find Cydia on an iPhone is to swipe down from the middle of the screen to bring up search and type “Cydia”. However, please note that it’s possible to hide the Cydia app, so this trick might not always work.

What happens if your iPhone is jailbroken?

Jailbreaking your iPhone removes some of Apple’s restrictions from the device and allows it to be modified in ways that the manufacturer did not intend. This means that you can download apps that aren’t available on the App Store and customize the device in ways that would normally not be allowed.

While this may sound tempting, the biggest risk of Jailbreaking is that it also removes the security restrictions put in place by Apple in order to protect your device and makes it more vulnerable to cyber attacks. Jailbreaking your iPhone will also void its warranty.

How can you fix a Jailbroken phone?

There are a few ways you can remove a jailbreak from your iPhone and therefore restore your device’s integrity. Firstly, if you used an app to initially perform the jailbreak, then it should have the option to unjailbreak the device directly in the app.

If this doesn’t work then, in most cases, rebooting your iPhone will fix a jailbreak by removing it from your device.

Can someone jailbreak my iPhone without me knowing?

Many jailbreak tools provide the option to hide the app icon once the jailbreak is complete. Therefore, if someone gains physical access to your phone for a short time they could jailbreak your phone and you may not know it has happened. It’s not generally possible to jailbreak an iPhone without physical access to the device.
