What does it mean to jailbreak an iPhone?
At one time or another, many people with Apple iOS-based devices, such as the iPhone, iPad or iPod touch, have looked into "jailbreaking" them. Jailbreaking means bypassing the restrictions Apple puts on the operating system and taking full control of the device.
Does jailbreaking your iPhone make it easier for hackers to hack you?
Jailbreaking absolutely makes your iPhone, iPad or iPod touch an easier target for malware. It completely removes the walls that Apple built into both iOS and the iTunes App Store.
Do jailbroken apps still work after an iOS update?
Jailbroken apps are not always supported in new versions of the Apple iOS, and each system update pushed out by Apple usually will erase jailbreaks and apps that depend on them. You'll have to jailbreak the device again, reinstall the unauthorized apps and hope they all still work.
Will jailbreak work on an iPad?
However, it won't work on an iPad, according to Brent Morris, a security analyst at GoPro in Carlsbad, California. Jailbreaking exposes the inner workings of an iPhone, iPad or iPod Touch to its user, which can be very useful. For example, installing a secure shell (SSH) client lets you securely move data between two devices on a network.
