Jailbreak Iphone 4s and Ipad 2 using IOS 5.01

What is Jailbreak?

Jailbreaking refers to the process of removing the imposed limitations by Apple on devices that run the iOS, including the new iPhone 4S. A custom kernel is uploaded into the device, which allows root access to the internal components of iDevices. These components include the operating system and hardware, should the person jailbreaking the device be skilled enough to do so.

2 Types of jailbreaks

• Tethered Jailbreaking – A tethered jailbreak will require the device to be connected to a computer or laptop every time it boots up. This particular kind of jailbreaking is the most reliable as the kernel is updated each time it is plugged in.
• Untethered Jailbreak – This kind of jailbreak allows the device to boot up and power on without the assistance of a computer. Best!!
