3 It Can Brick Your Device
There’s an unfortunate side effect of jailbreaking your iPhone: It could potentially brick your device. That means you’ll never be able to use it, in any capacity, ever again. In certain instances, the process of jailbreaking an iPhone has rendered the device completely useless. This has happened more often with jailbreak software and tools that are in beta stages.
Other times, tweaking and adjusting the settings within a device can also brick it. And if this happens, you’re in a tough spot because it will void your warranty.
