How to jailbreak iPhone 3.1.2 (3G/3GS root guide)


23.02.2010

Jailbreak is a process that allows iPhone and iPod Touch users to run any code on their devices, as opposed to only that code authorized by Apple. Once you jailbreak, iPhone users are able to download many applications previously unavailable through the App Store via unofficial installers such as Cydia; Icy; and Installer, as well as illegal pirated apps. A jailbreak iPhone or iPod Touch is still able to use and update apps downloaded and purchased from Apple’s official App Store.

In order to enable tethering on your iPhone with the 3.1.2 installed firmware (read HERE), you need to jailbreak it first.
