Currently, redsn0w version 0.9.6b5 allows you to perform a tethered jailbreak to your device that has already been upgraded to firmware 4.2.1, which means you need to use redsn0w every time you boot the device, otherwise all your jailbreak data gets wiped. However, it will NOT unlock the device, enabling it to be used with different GSM carriers worldwide.

Ingredients:

• An iPhone 4 updated to firmware 4.2.1

• iTunes 10.1 or later
• redsn0w 0.9.6b5 for Mac.

2. Click the ‘Browse’ button below the text, it will ask you to locate a firmware file, choose the 4.2.1 firmware for iPhone 4 and click ‘Open’.

4. Then, choose if you want to install cydia and click the ‘Next’ button again.

5. Now, it will ask you to connect the device to your Mac/PC and then turn it off, do so and click ‘Next’. Now follow the on-screen instructions to proceed.
