Edit: This might be patched by Apple in newly shipped 8GB's.. some people get error 28 who have recently gotten an iPod Touch 3G 8GB. Edit 2: What you guys might want to try on your iPod Touch 8GB's 4.0 is get the 3.1.3 2G IPSW and use that WITH latest version of iTunes!

Hey guys, I figured out a way to downgrade from iPod Touch 3G 3.1.3 to 3.1.2, as well as 4.0 to 3.1.3! !Update! Follow these simple steps! MC Models! 1. You will need to download the 2ND GENERATION 3.1.2 Firmware, or the 3.1.3 one if you are currently on 4.0. The name should be iPod2,1_3.1.2_7D11_Restore.ipsw, or iPod2,1_3.1.3_7D11_Restore.ipsw. I will not be telling you how to obtain these. Sorry. 2. Open iTunes. 3. Make sure your iPod is connected, put it into DFU mode by holding the power(top left button) and home(circle on bottom) for 10 seconds, releasing the power button after the 10 seconds while still holding the home button. 4. You should see a message appear in iTunes saying it has detected in Recovery Mode, press OK. 5. Hold Shift+Restore on windows, Command+restore on mac 6. Choose the iPod Touch 2nd Gen 3.1.2 or 3.1.3 firmware!! 7. Let it's do it's thing. 8. If you did this for a 3.1.x jailbreak, use spirit, if you wanted the 4.0 jailbreak, use iThemer jailbreaking tutorial using iH8sn0w's sn0wbreeze. 9. Enjoy!
