What is the difference between jailbreak and non jailbreak

Lots of custom ROMs exist for Android — everything from large projects that support a variety of devices to custom ROMs with a few theme patches some kid whipped up in his spare time.

However, many Android phones come with locked bootloaders. Unlocking the bootloader allows you to install custom ROMs — alternate versions of the Android operating system. Nexus devices which are also intended for developers can be easily unlocked. Unlocking a boot loader can theoretically allow you to install non-Android operating systems, too. The desktop version of Ubuntu can be installed on the Nexus 7, too. Of course, the operating system must be built to be compatible with a specific device.

If you insert a SIM card from a competing carrier into the phone, you will see a message indicating that the phone is locked and cannot be used with the SIM card. Unlocking a phone allows you to use it with a different SIM card — either to use a different carrier while travelling or to take your current phone with you while switching to a new service provider. You will generally need an unlock code to unlock the phone. Many carriers will unlock phones once your contract is up, while phones bought outright without a contract may not be locked to a carrier at all.

There are security risks to jailbreaking your phone. While jailbreaking gives you more control over your device, it also gives all the apps that run on it more control.

Jailbroken phones are much more susceptible to viruses and malware because users can avoid Apple application vetting processes that help ensure users download virus-free apps. Jailbreaking enables software piracy, so apps and games can be distributed for free. This means you are placing your trust in the developers of all the apps you install rather than Apple. Data from banking apps, stored passwords, and data from social media accounts could be at risk if this information becomes accessible from a jailbroken iPhone.

As mentioned above, this risk became apparent when an iOS jailbreak malware called KeyRaider stole , Apple IDs and thousands of certificates, private keys, and purchasing receipts. Ultimately, victims reported their stolen accounts showed abnormal app purchasing history, and in other instances, phones were locked and held for ransom. Aside from being at greater risk of malware , jailbroken iPhones are often filled with bugs that could keep crashing your phone and disable other important features.

As smartphone usage continues to grow, so too does the risk of mobile crime. That is why it is essential to stay informed about the latest threats and scams, and to have comprehensive mobile security installed on your device.
