Many of my readers asked what is jailbreaking? How do we jailbreak? What is the purpose for jailbreaking? I would like to answer them all through this tutorial. Here we will learn how to jailbreak iPhone 4 and why people jailbreak all iDevices like iPad , iPhone and upcoming fourth generation iPod touch 4.
What is jailbreaking ?
Jailbreaking is modifying the iOS firmware running on a iDevice [iPhone,iPod touch,iPad] to allow it to run unsigned code in order to gain access to files that Apple wouldnâ€™t normally allow you to . Jailbreaking will enable your device to install and run unofficial application installers to your phone , popular among them is Cydia .
Why do we jailbreak ?
As i have mentioned above , jailbreak allows you to install Cydia , an App Store like application installer. Cydia comes with numerous apps to run various applications like MyWi , which can turn you iPhone into a WiFi hotspot , and it can then work as a modem for third-party devices. Secondly , a jailbroken iPhone can virtually do anything you want it to do . A jailbroken iPhone can be unlocked using UltraSn0w ( an app that runs only on Cydia) , that allows you to choose your carrier. Forgot to mention that , iPhone’s usually comes locked to carrier’s in most countries. Factory unlocked iPhone are expensive deal. So people go for cheap factory locked iPhone and then jailbreak and unlock it to use with their service provider.
