This video is on Jailbreak/Unlocking your iphone 3g and Jailbreaking iPod Touch 2nd gen (NON MC MODEL). You can check your iPod Model by going to settings on your ipod then general then About then look for Model.
Itunes 9.2 is required to do all this.
You will be using Redsnow 0.9.5 to jailbreak and Hacktivate your iphone 3g and/or iPod Touch 2nd generation.
If you are on 4.0.1 firmware then simply point iOS 4 in redsnow to jailbreak your devices respectively.
IMPORTANT 1: IF YOU HAVE AN IPHONE 3G USING AN UN-OFFICIAL SIM CARD (or No Sim Card at all) THEN AFTER UPDATING YOUR IPHONE FROM ITUNES TO iOS4 , YOU WILL SEE ITUNES LOGO AND USB LOGO ON YOUR IPHONE SCREEN. DO NOT PANIC. AT THIS POINT SIMPLY CLOSE ITUNES AND RUN REDSNOW 0.9.5. THIS WILL HACTIVATE YOUR IPHONE 3G AND OPEN IN NORMAL MODE.
***DO NO PANIC***
For now, the redsn0w beta release supports only the iPhone3G and iPod Touch 2G at today's 4.0/4.0.1. It's still a beta, so you'll need to let Cydia reorganize, reload, and update after using redsn0w.
