However, iPhone Jailbreak can solve all of these problems and it is legal. This guide should only be attempted on iPhones with 3.0 firmware or below only and will teach you how to unlock an iPhone.
In order to learn how to jailbreak your iPhone, you will first of all need to download a few programs. You will need to install Redsnow for windows, Mac or Linux and the 3.0 firmware for iPhone 2g. You will also need to download the 3.9 and 4.6 boatloaders if you need to unlock your iPhone in addition to the jailbreaking. Save all of these downloads in a folder named, 'jailbreak' so that it is easy to find.
Starting the jailbreak
Launch the Redsnow programme and click browse. Find the 3.0 firmware that you have downloaded and select it. Then click the 'Next' option to restore your phone to the 3.0 firmware.
Choose to install the Cydia programme and unlock your iphone. This then allows the iPhone to be used on non-approved Apple carriers.
After you have chosen to unlock your phone, Redsnow will ask you to the identify the bootloader file that you downloaded in the first step which you should say yes to.
Next, turn off your iPhone but leave it connected to the USB port and click the next option on the computer screen. From here, follow the on-screen instructions. A tab will appear on the screen which will state that the computer is jail breaking. This process should take a minute or less.
